forward with indycar because we're with everybody xiao powering progress i'm melanie zanona in washington and this is cnn on your screen right now, you can see what we've been watching develop over the last hour or so, police have moved into columbia university to move those pro-palestinian demonstrators out of the building that they've occupied since last night, hundreds and hundreds of law enforcement. >> you can see have swarmed onto the campus or in the case of the screen, you're looking at right now, the picture you're looking at right now, just off campus, we have seen law enforcement move people onto buses presumably under arrest. we've also seen the police simply move people off the campus and let them go on their way. we have seen no violent encounters but billy, between police and protesters as of now, when we have seen police move into hamilton hall itself, that is the building that was occupied overnight by these protesters. let me read you a statement from columbia university which explains how this all has been taking place over the last hour or the statement reads a little after 9:00 p.m. this evening, the nypd arrived on campus at the university's request. this decision was made to restore safety in order to our community immunity. we regret the protesters have chosen to escalate the situation through their actions after the university learned overnight that hamilton hall had been occupied vandalized, and blockaded. we were left with no choice columbia public safety personnel were forced out of the building and a member of our facilities team was threatened. we will not risk the safety of our community or the potential for further escalation. the statement continues, the leadership team, including the board of trustees, met throughout the night and early into the morning, consulting with security experts and law enforcement to determine the best plan to protect our students in the entire columbia community. we made the decision they say early in the morning that it was a law enforcement matter and that the end nypd were best positioned to determine an execute the appropriate response. this is important what they say next, we believe that the group that broke into an occupied the building is led by individuals who were not affiliated with the university sadly, this dangerous decision followed more than a week of what had been productive discussions with representatives of the west lawn encampment. they go on to say they'd been moving people out all day resulting finally, in what you are seeing on your screen tonight. this is just one of the images that we have our eyes on right now again, this is just off-campus. let's go right to julia vargas jones cnn producer who was on campus for most of the de, right in front of hamilton hall, but was just moved off. julia tells what you're seeing now, what's happening, where you are john just going to swing around a little bit so you understand where we are. this is amsterdam avenue and this is one 14 up this way. i don't know how much you can actually be. i'm sorry, i'm just kind of walking through the ground. this is where we were pledged were pushed out columbia university through those gates and pushed into this it's not really a cattle because we're not getting arrested, but we were pushed into this area with barricade myself. >> i'm assuming that columbia university's and hundreds of others, people that were protesting in sayyed. were also pushed out. people that were making this human chain outside of hamilton hall. >> they were pushed out. >> they made another human chain outside, hundred and 14 feet and eventually nypd just forcefully remove them. they did not get arrested. this is like teeth difference here. they looked like for me, i can't tell you if there were not and then we've got pushed into this little area right now. it's a standstill if i. can go into get my thing it's very it's very difficult to understand where i believe wants us to go eventually right now, we're just sitting here at this corner in the middle of the protests with nowhere else to go up here, up this way, we have bosses and mike pz boss says, i can't tell if there are people inside those buses or not moving that way. and then now we see a emergency medical vehicle making turning into one 14th street they are going this is the way that they pushed all in all of the protesters and journalists. so not sure all of this is blocked off and believes. is not letting us move anywhere else. this is where we have to say for the time being, julia, it hang on one second, just so people understand there is amsterdam avenue which runs north and south. there is broad wheres runs north and south in between broadway and amsterdam is columbia university basically between 143 in 100. or higher and 18th street, if you go up a little bit further north of that so julia is on one end of the university where people have been pushed out. two questions quickly, julie, one, it looks like it's raining now, if you can confirm it's raining now, which may have an impact it may have an impact on the crowds. they are that people will still outside and who more than people you're looking at a map right now, just what is describing you can see north-south broadway, who are the people standing beside you john, there is no nowhere for us to go. >> i don't think that we can get out of here right now this is i see a lot of students, a lot of students press lot of people with journalism, which is where i what i'm affiliated with as well and we were asking that more just outside hamilton hall, a protesting, so it's a mix of students, people that were there protesting that we don't know in if part affiliate nobody university are not this is just the situations and then just pushed us all into the same corner at one and amsterdam all right. >> julia vargas jones stay safe. don't go far let us know if there are any developments where you are. want to bring in john miller, cnn senior law enforcement and terror analysts right now. john, i have to say over to the corner, my eye saw you on the phone, which generally means you're finding out information once the latest your hearing on what is happening think up at columbia. >> so police obviously swept the group that was in front of hamilton hall off some of them who ended up on those buses, are those are gonna be people who are in custody those who are swept out through the gates are people who elected not to be arrested and agreed to leave so we're going to have some arrest numbers, but probably coming to us later because they're operating out of multiple locations to do that tally. they did make entrance into hamilton hall from what i understand. and this is all preliminary, so you have to assume some of it could change that there weren't a great deal of people in terms of numbers inside the building when they made entry, they used distraction devices or what we would call a flash bangs. these are things that go flash and then bang so that they could overcome any resistance. booby traps or anything that was waiting for them inside. and then they did a floor by floor search, which did not produce a lot of people. they're going from the second to last floor now to the top floor. so the building is nearly cleared in the first instance, they'll do a secondary search just to clean up behind that but that's pretty much where we are now. so if you talk about what, what are reporter on the scene was saying about people were pushed out, they were put into pens it feels like from a tactical standpoint, they want to create a corridor, a portal so that when they have these people who are under arrest on these buses, that the buses will have a clear path out and that the street will be open and not occupied and they can take them down to this mass the rest processing center unknown number of arrests. >> you say. so far dozens, hundreds, any sense i'm going to just based on the visuals, it appears to be at least dozens that could trip the triple digits because there were large number of people there. >> but as we learned from ms vargas, a lot of them more pushed out of the gates. and those are people who decided to forgo the process of being arrested. now, things have developed their over the last couple of days protest leaders from out of town, people like lisa 50. and who is the author of the book? shut it down? who is very adept at coaching groups on how to do protests, how to do disruption how to do vandalism and physical damage, how to handle mass arrest situations have been up there talking to them, working with them. so a lot has changed over the past 48 hours in terms of where they were. >> all right. we are being told dozens have been arrested. that is so far we also did get word from julia vargas jones on the scene that a lot of people were simply moved away, pushed away and i imagine it is to an officer's discretion whether tool right asked are just remove people from the premises. john miller just reporting that the police who did enter hamilton hall used flash bangs. they move through fairly quickly and there were not a lot of people actually in hamilton hall and they are close. >> they think to clearing the building or at least seeing every part of the building one interesting point to add there what we're seeing on social media as reports from students saying that the tear gas was deployed. the nypd almost never uses tear gas and saying that they did not use tear gas tonight. i think that's the smoke from the flash bangs that they're probably reading as that yeah. >> and you were looking at police now walking past one of our camera is right there in a mass movement, unclear whether they are moving to hamilton hall 100 moving away from hamilton hall with us that also it's philippe rodriguez then retired nypd officer. it's just explain what john just said to us about using the flash bangs to get and we did hear from a police spokesman a short time ago, who did reiterate what john just said, which is that the nypd does not use tear gas? correct. but how do you imagine they went through that building? >> it's almost like a tactical situation where the almost thing is to get through it safely so a flash bang is just a very long concussion grenade and it's made to do is disorient the person. so if they had a preemptive type of tactical de, that they're going to attack an officer it now make some also a little bit dizzy because it messes with equilibrium. so it does give the us is a tactical advantage. we never want to go in there with the use of excessive force. so we can mitigate that from the beginning, it was a good tactical choice to use them it's just not often seen in new york city. shimon prokupecz, if you are with us, not sure if we have shimon right now shimon, you can hear me. >> i am here. i'm here it was a sense of what you're seeing okay. >> so we're on amsterdam one-sixteenth, so we're outside hamilton hall here, but this is where the police went in you know, it's just such a struts, such strategic planning that went into this you just wonder what how much time was the nypd planning for this? because the way they came in here just over my left shoulder i'm going to try to show you. can we just show i just want to show this side over here. is there a way to do the number of emergency services vehicles? john, i've never seen this kind of response at a scene. i mean, there are at least a dozen to 20 emergency services vehicles here then of course, we saw many of them walk to this heavily armed truck. it's what they call a bear cat. and then they walked up through that window and then entered hamilton hall. it's just a stunning pictures to think this is a university cullum columbia university that the police are entering in such a way because the doors were barricaded. the group broken in the morning and it's been there all day. they unfurled flags here or signs here today, they're up on the roof who i want point. so the nypd really spent a day planning for this and then surged i mean, hundreds, if not at least 1,000 officers here. >> i mean, you have officers from the search teams, you have officers from other precincts, the emergency services officers. >> the response was just enormous now, most of the officers are just standing around. we're seeing some protesters were hearing the chance a are gathered outside here. some are up here on a bridge, all watching to see what's going to happen and what the next steps will be right now, all eyes and everything is on hamilton hall as we await to see what the next steps are are the police going to bring anybody out from inside and you can hear the protest. is there shouting shame at the officers every time a group of officers would move through an area, we would hear that shame, shame towards the officers. but this is such an escalation here. but what started it? we have to remember is what happened here early this morning you know, the fact that you had outside groups the nypd has said so the college has said so the fact that they broke in to this hall, the fact that they snuck onto the campus we believe someone who has not gone around 2:00 yesterday when the campus would allow the press, the media to get on on on the campus of the college they snuck on and so they spent the morning, early morning planning this and they got inside and this was a game changer and just talking to sources all day john, they were waiting, they were waiting all day to get word from the college that they could do this. the nypd wanted to do this. they felt it was necessary, it was needed, and there was a lot of concern that if they didn't do this today this would only escalated. there were concerns for other members of outside groups coming in trying to escalate this even further sewing doing this, i mean, these are going to be images that are going to are going to last a lifetime, right? this kind of response on a university in the united states in many ways, sometimes it's just unfathomable and such, in such a situation. but that's exactly what happened here. the response was, john, i've covered so many protests through the years here in new york, especially i've never seen a response like this. they came prepared they came in force and they came to send the message and right now, we're just seeing so many of the officers still out here standing around. things are calm, people are chanting we could even here are some. it sounds like chance that are coming from inside the campus as the police are just standing around. and right now really drawn. all eyes are on hamilton hall as we await to see if anybody's brought brought out. and what the next steps are here. >> yeah. shimon prokupecz, who was on the street. they're near that enormous police presence. i would just note that as big as the police presence and as many of these protests as we've all covered, one thing that we have not seen here yet that we often see almost always see is a rash of injuries or violent clashes. we haven't seen that yet with our eyes here. that's not to say it hasn't happened and we won't learn of that shortly. but this has seem fairly organized so far. let's get right to miguel marquez. right now, miguel, you are just so people know it's the right side of our screen where miguel is. tell us what you're seeing miguel yeah. >> so we're on 114th street just near amsterdam avenue. this bus that you are looking at here, this is the second bus filled with the recipes that is now leaving this area it's heading toward amsterdam avenue. when it gets down there, the last bus that tried to get out, you can see all the people on there that are arrested. still shouting, still yelling, many of them wearing keffiyehs. there's a large number of people who are trying to block the buses on amsterdam avenue as they get down there. police moved down. there are a large contingent of police officers down there to control that crowds the buses can get out. we have seen dozens of people arrested the gates just here where i'm sitting next to. >> if you go up that gate and took a rights, you'd be basically at hamilton the hole. >> so it sounds like if there weren't many people in there that most the people that we've already seen commodities, gaetz, probably came from hamilton hall. what i'm curious about are the account meant if you went up this gate and went left, you'd end up near butler library, which is here. and the encampment, which isn't a center lawn of columbia university. it's not clear how many people they've moved out of that encampment. >> can would just move around. >> you can i don't know if you can see it, but there is a large number of police and protesters are trying to stop the bus down at the end of the streets the bus has gotten out though it's not clear. so there were protesters. much of the day much of the day come back over here there were protesters, much of the day at amsterdam avenue. so some of those people may have been arrested. there were also protesters at the main gate, columbia university veins gate on 116 street, about four hours or they just marched off. they were 200 protesters and they just marched off with you at north. >> it sounds like they ended up at city college is about 20 blocks north and they had the flares and they were going to city college and it sounds like it was a bit of coordination on the side of, protesters the protesters on the hundred and 16 sayyed, were there. >> they were going through with everybody the tactics that they were going to use tonight and what to do if they were arrested? didn't how it was already go. we may be bringing up more arrestees now out of this gate, this is what we've seen. most of them come out some of them note this just was like a faculty member or somebody who's coming out of the gates right now, there were there are workers that are coming out as well that we will see some times but most of the arrest you've seen tonight have come out of this gate. we haven't seen any for quite some time now. but there may be arrests around the corner where shimon is on amsterdam avenue it looks like buses are moving over to that direction as well. as they can bring people out of that area as well. >> john keep us posted as to what you see there strictly if there are more people being brought out, arrested, let's get back to julia vargas jones to give us a sense, julia of what you're seeing. and i'm glad we can see you on the right-hand side of our screen. >> john, add two things. one, we're seeing a staging of nypd coming out of 114. you can see here behind me, right behind them. i don't know if you can see there are people coming out of windows from i believe this is hamilton hall coming out john jay, john jay. >> i'm sorry. this is john jay buildings and building right next to it showing with their phone speaks to the whole question, something that i've mentioned before, it's like, what's this mean for the columbia community? speaking? now, also as a student here, it is unfathomable that this is happening on our campus. this level of division, this level of i know we said there hasn't been there haven't been violent altercations. that is true. i have not witnessed any violence happening. here. where we did just see a boss with people nypd blast with people in it, they had cahiers. >> i don't know. i'm guessing this is the people that were outside or inside of hamilton hall that just went up amsterdam towards the i suppose miguel's location just a block north of us overall. >> i mean, now, finally, the good news is that it's raining. so it's giving us a little bit of a spike, but like i mentioned, rick kind of kettler here, john, there isn't really anywhere for us to go. >> i will waiting for what are some of the nypd of whether or not we can go back inside the columbia campus as of now. i'm really not sure. i mean, i have my sun id here and i don't know what this will do. i can actually go back inside at all. >> i think we're gearing up to have a long night and it in to some on-court earlier. >> this has been so organized and cause and the level of a police presence giving me a little bit of flashbacks and 2020 and the presence across the us. >> but it's there are no altercations that is no common. >> like i mentioned earlier, some of the students that did not want to leave that university. instead of being arrested, they were just removed. >> so the nypd grabbed a couple of people and push them out meaning, i think that there is a level of concern for the optics of this as well. >> it really is an attempt to, if this is really an attempt to de-escalate this has to be the approach that they take julia hang on one second. >> you may be interested in this information as a columbia student, we're just getting word that columbia university has made a request with the new york police department to retain a presence on campus through at least may 17, they say that is to maintain order and ensure that encampments are not re-establish. that was from a letter sent by university president minouche shafik to michael gerber, the nypd's deputy commissioner of legal matters. so julia, there will be a police presence at columbia for some time for several weeks, and i should note that is through what i believe to be columbia graduation, which is may 15th. so the police will be there in some way until may 17. how do you imagine that might go over with your fellow students at the university? >> well i mean graduation is may 15. that is my graduation as well. john, you're high fat. i have family coming from brazil to come watch me, walk across the stage and get my diploma. but and i hope of course, as everyone does, that this can happen. but at the same time there, are climates for celebration, for graduation to move on. i mean, i think that i spoke to a lot of students on campus today and didn't work just dealing caught in-between i don't really see celebration be something that we flocked to in the coming weeks. if police is going to be on campus, that will even dampen the moon even more. i can't imagine people wanted, i'm interested to see who actually had so here's another box i can't quite see inside, but yes, it looks like people with their faces covered could be us i'm not a bus of her being taken away presumably arrest said and you hear the protesters chanting shame at the nypd files, john and again, the news is is that the new york police department will remain with a presence on campus through may 17. >> may 15, of course, is graduation. were are julia vargas jones will be walking, earning her degree. i have to say you've more than earned or journalism degree three over the last 24 hours or so, julia. so celebration or not. congratulations to you on that and all the work you've done. we have much more coverage just ahead. we are just getting word that some of the protesters have moved about 20 blocks north. that's what you're looking at right there. that is sitting the college for those who know new york well, the campus there, we're gonna get a live report from there right after this after advil. >> let's night in what about your back for ads? >> advil

columbia university, entering hamilton hall where protesters had taken over the building sees the building overnight last night, the police have now moved through the building and we believed removed almost everyone from inside. we are told there have been dozens and dozens of arrests so far based on the bus as we've seen, leaving, it would be easy to assume that there have been over 100 arrest so far, but we don't have an exact number on that just yet let's get to miguel marquez, who's standing by just on the outskirts of the university. and just so people know what they're looking at on the screen. on the well, okay. let's get to miguel first and then we'll reset what those other patients in a second ago. what are you seeing what you're looking at here is yet another person who's been arrested and brought out from the other gate, the gate that we are at earlier that we're on 114 street between broadway and amsterdam. >> we're now closer to amsterdam. we've seen lots of arrestees coming out of here. there's now another arrestee going into a forth bus rights right in front of us and it is not clear. i'm watching that gate down there. police appear to have formed a core on coming out of that gate and they're pulling people out of that may be people coming out of the encampment. it wasn't clear to us covering this earlier in the week how many people were in the encampment? they had lots of tense, but but we think there were only maybe a couple of dozen, few dozen people who were in the encampment so far tonight, we've seen in the dozens arrested. i don't think we're at 100 yet, but it's hard to tell. we've, we've seen three or four buses leave here now there have been some arrests on amsterdam avenue as well around the corner from where we are but it seems right now that there are at least several dozen arrests here at columbia university. i will say two weeks ago when they made arrest, hundred and eight arrests that then kicked off this backlash of encampments across the country. 70 of those 108 were not columbia students. so the university nypd, looking at that tonight as well, the protesters do seem to have their own coordination. they were there had been protesting on amsterdam avenue for much of the day. they remain there all night and it seems that some of those protesters that were outside may have been arrested as well, but there was a large group of protesters who went to the main gate on broadway, hundred and 16th and broadway police then shut down all of broadway, both north and south south major thoroughfare. >> those protests, again when uptown, it seems to city college and you had protesters sort of coordinating protests at different colleges. all at the same time. john and again, we're seeing pictures up at city college to a 20 bucks north of columbia right now, miguel, thank you. >> standby for a moment, if you will. joe jackson or legal analyst is here. joey, we talk about dozens and dozens the rest. what happens to these people on the buses? what does it mean to be put under arrest for tonight and for the next several days? yeah. i think john, the prosecutor here avenue bragg, has a decision to make and what that decision is is what he's going to do with they're going to be a distinction between students. and if so, do you criminalize this? so do you offer them some? resolution to the case which respects their right to protest? but again, you know, has some semblance of law that has to be mixed into it. and do you distinguish the students from the nonce? students write how they got onto the campus. what specifically did they do? what they peaceful and so in essence, what will happen is that they will go to this arrest prostate processing load occasion at some point there'll be arraigned. what that means in english is there'll be brought before a judge. there'll be formally charged with either disorderly conduct or criminal trespass or whatever the the appropriate charges are depending upon the specific conduct at that time, there'll be released. right. there are bail reform laws in new york. there's nothing violent nature that is a blessing right? we're seeing optics, not of any violence, not of any interactions of a negative variety, but of officers having taken control. i'm sure that i'm sure john millikan give us a course on how they sat them down and said, look, this is what we're going to do. this is how we're going to do it. the optics need to be what they have to be. and i think they did that very successfully. thank goodness for that. and so john will happen is after their process and released, there'll be a date for them to return and that interim period, prosecutors will make an assessment as to how to dispose of the case. generally speaking on a first terrestrial, either get a disorderly conduct or something known as an acd. what does that mean? and a german and contemplation of dismissal, you started trouble. you do everything right. you're case will be dismissed. it will be sealed. you'll go on with your life. that's how generally it will be done in the absence of any aggravating factors which demonstrate that the protesters at issue did something that that was aggravating other than being in a building occupying it and really peacefully protesting and the way they think was appropriate and on the left-hand side of your screen is city college of new york ccny. >> and before we had a shot of the arch there and i've told by by people sitting with me here, that city university is actually often used as a facsimile for columbia university and television shows and movies. so if we get that picture of the building backup again, it may look familiar to you. it's actually about 20 bucks north of columbia or a lot of these protesters have moved so that sound those demonstrations you're seeing right now, not actually on the columbia campus, which is more or less been cleared out by police over the last couple of hours or so with this here, also is professor her alexa okay. forger brooklyn law professor, but also somebody did a fellowship at columbia for two years and look there are legal questions now, me, columbia face legal questions before inviting the police in. again today. and now with the invitation for the police to stay until may 17, there are more questions about how they will treat the situation they're exactly and students have all people have a right to peacefully protest to speak freely about issues and their rights do not go away once they approach this sort of college gates. and here we have quite literally the college gates and there are sort of measures that a university can take, both private and public students. speech cannot disrupt or impact the main thrust of university, which is learning and this is an interesting period right now the academic calendar, many classes have ended. we are in this sort of dead space when students are reading, they're preparing for exams, they're turning in papers my understanding is that many of the classes have moved online, virtual. >> yes, weaker. so the last week or so, some classes are not even meeting many classes many exams can be taken virtually are not on campus. we dealt with this and academic institutions during the height of the pandemic. and so i think what's happened we've recognized it that with police force been on campus until may 17 columbia really wants to have a graduation. they wanted to clear off that lawn. that beautiful green lawn is where commencement happens each year and so i feel for these students they they're engaged, they're young people. they know what's happening in this country and around the world and the tools that they're using or their minds, their voices. many are wearing confuse. they've got signs. there the chanting, and they really want to show that the students at columbia and on college campuses across this country, that students are concerned for what's happening in gaza students are concerned with what's happening to palestinians. and my knowledge is that many students i'm professor at brooklyn law school. i advise my students fans who are part of the national lawyers guild chapter, student chapter. students for justice in palestine. they're all in conversation with each other. and supporting each other for really the collective movement that we're seeing of young people. >> you're looking again at light pictures just outside the campus of columbia university. the police have moved in there. they move the cameras out. we don't have any picture from inside the campus anymore outside hamilton hall. are julia vargas jones was outside hamilton hall all day reporting from the scene, providing really an exclusive look of what was going on. julia, you boulden moved off campus now and we see you just outside where there have been i think some some words shall we say between the demonstrators and police it's getting a little no all right. >> we'll have a hard time hearing julia right now. julia, hopefully you can get if you can hear me, if you can get your microphone fixed, but i do believe what you were saying is there have been some shouts from the protesters toward the police, though the police were there standing, the police were standing there peacefully. the protesters separate from them i'm also standing there on the right-hand side of your screen. we can see people i believe the police officers, i think leaving hamilton hall. where they had gone in through the window through that ramp actually, let's get to miguel marquez right now and tell us what you're seeing from where you are so we're just watching these buses as well. >> but were turned around and i've turned myself around and look down amsterdam. there are reports that there as smoke coming off the top of hamilton hall. we know that protesters were up on the roof of hamilton hall i don't think ken can you can you shoot this can use see the smoke coming off of that the smoke. can you see this? >> we're live can can you exhaust from a billing you think it's just exhaust their are so they're reports that there is smoke coming off the hamilton hall. >> some police have gone down to look at it. i don't see a ton of smoke coming off here. it may be just exhaust coming off of the hospital. that's across the way from us. but there were protesters on the roof of hamilton hall earlier, police say they use flash bang grenades, which could spark a fire if there's something combustion well that they hit. but it's not really clear what's happening. it is very clear. seat calm seen on this southern hundred and 14. we haven't seen any more arrests were quite some time now. there is one more bus that they have down there that they are slowly moving people into. but we haven't seen a time and it doesn't appear to me that that is if it is smoke, it's not very heavy smoke. it looks it looks more like exhaust but i don't see anything coming out of hamilton hall right now giulia is down amsterdam so maybe shimon, they might be able to see more down there. >> all right. >> we'll check it with them in a bit. miguel, i'll keep us posted as to what you see going to bring back in our chief law enforcement analyst, john miller, who's here with us as well, and john, anything new your hearing before you had her that law enforcement had moved through almost all of hamilton hall and they really weren't that many people inside. >> that's right. so, you know, barricading the buildings surrounding the building there's two interesting possibilities here. one is that when it was clear the police, we're going to come and clear the building. the people inside might've gone outside. as joey jackson will tell you, the charge oh for being inside and criminal trespass might come with a burglary charge or more. so that might have been a tactical legal judgment on that point. but what we're watching here is that truck is is the big bear that has the ramp that they can use to do an entry into a location from, an upper floor as opposed to from the ground floor and they are wrapping that up to get their ramp back down. that building is effectively cleared. now, what we looked at a minute ago was the emergency service units driving away so most of the tactical piece of taking that building back and clearing the inside appears to be complete just from what we're watching here. we've seen the buses because they've pushed the crowd outside the gates and into pens that the buses, police buses carrying the arrest have cleared the area and are on their way to map c or the mass arrests processing center down at headquarters. in terms of the demonstrators, you're going to see two things a number for them. will go up, likely to city college about 20 blocks north at 140th street and broadway or amsterdam rather you'll see others go down to the arrest processing center where they do a different kind of jump demonstration called jail support where they protest outside all right. >> everyone standby for a minute again, you're looking at live pictures on the right-hand side of your screen, columbia university, where police have cleared out. we believe almost all of hamilton hall on the left city college polish were there are still demonstrations or live coverage continues right after this how could anyone possibly know that every single

solomon in new york and this is cnn all right, you are looking at live pictures. >> this is a city college in new york, which is about 20 blocks north of columbia university. of course, columbia university, about an hour and 45 minutes ago, police moved in to remove the demonstrators who had taken over hamilton paul many of the protesters move north to city college is what you're looking at right now. and we did just see a brief skirmish may lay between the police and some protesters. it did look like a few arrests were made, but it was quick and now it appears that those clashes, as they were, are now over. we're going to keep our eye on that to see if the situation develops. once again. the meantime, i want to bring in mahmoud khalil. he is a second-year graduate student who has been leading negotiations with the columbia administration on behalf of the pro-palestinian protesters mcclure, thank you for being with us. i just want to know your reaction to what has happened tonight hi. >> hi, john. today is another disgraceful and shameful day for the columbia administration. on this day, this is 55 years and it very city of the 6868 demonstrations and protests that happened actually, add the same building that the university broads nypd to invade and to address these peaceful peaceful let's traitors and the inverse of things about this would discourage students. four calling for the end of the war in gaza and the end columbia's investments in the companies that are investing and the genocide and palestinian people since we started our negotiation last lesson the friday, the university did not deal with this, with this movement as an actual movement, an anti-war movement instead, they dealt with it as an internal student discipline matter they've negotiated with us about bringing food and blankets to the encampment the refused to acknowledge that this is actually more than that. this is a nationwide movement. this is a movement that as the columbia to divest its investments from companies that are fueling the word and gaza right now so what i'm feeling right now, i'm feeling disgrace by this institute. >> when hamilton hall was taken over, whether it was part of, as you say, a larger anti-war movement or an on-campus disciplinary matter? what was the expectation that columbia would do once a building was seized in windows were broken and vandalized the autonomous group decided to take that building when they felt that the is not answering their demands. >> the inverse is not dealing with them seriously. and the university's actually just eleni, alleviating them. so they had to do something. so the university can actually take, take their demands seriously. these students have been demonstrating columbia since, since october. every week, they would demonstrate campus at the university would answer, only buy more discipline. and by suspension of, of, of the students. so when they last week when they establish a very peaceful encampment on the east lawn. the university, you did not wait a minute to bring the nypd, which in fact, the president herself said that this the first call for nypd was some somewhat not a wise decision. and exit prevented the issue columbia. yeah. here we are again bringing more force, hoping that this movement wouldn't continue. and woodstock, and in fact, shafi'i, president jp of columbia requested from the nypd to stay on campus until may 17 after the graduation to make sure that no students are on campus to reestablish such encampment. encampments, or two actually practice their first amendment i have to let you go mouthful, but we'll the protests continue even with the police presence until may 17 i expect that i'm not sure how how would the presence of the police would change this the students will still have their rights to protest and i'm very confident that students will will, will continue this movement even after all this brutality against them all right mathematica leo, thank you very much for being with us. do appreciate your time with us here have been watching this is is we put rodriguez, former mib police officer we did see a little while ago those arrests up at city college, just tell me what you've been seeing in terms of how the police and law enforcement has been behaving on the ground you know what, they have to be commended. i saw a lot of restraint. we saw the team tactics was being done correctly. they were working together as a group. we didn't see these wild swinging and buttons like we've done in the past. you don't want to arrest had to be made. they work together to take that person and with a minimum amount of force and to de-escalate by having a large presence of officers. there at the scene what's it going to be like for those officers? >> you've got to be up there until may 17. it's going to be difficult to really as it's going to wear them down. >> but nypd is one of the best police departments when it comes to deal with large-scale situations. >> and professor looks again, who was at columbia for a couple of years what's gonna be the reaction on campus to a law enforcement presence until may 17. and we don't know what it will look like yet. maybe we can talk about that in a second. but what do you think the response will be on campus? >> yeah. i don't think it's gonna be a comfortable place to be for students. i don't think it's gonna be a comfortable place for families to comments not for graduation and celebration the climate is going to be chilled. it's, it's gonna be a different place to be at and really what columbia has done and bringing in the nyt mpd is to overwhelm the student population with just the sheer presence and numbers of force. just just being there is going to make a difference. i can imagine that students will still demonstrate in whatever way that they can they feel very strongly about columbia divesting from supporting what's going on in gaza and so i don't imagine that that will end. it might look a little different, but i think we're still good to see students demonstrating or be go marquez, still standing by just outside columbia university, miguel, i understand you've got some new information nypd just brief a short time ago here on one 14, they say it's done. >> there is hamilton hall has been cleared and is secured. the encampment's that was out there for the last couple hello. weeks. that too has been cleared. the only thing out there right now are tenths and their personal possessions. but everybody that didn't want to leave and didn't want to leave the camp. he was it was arrested. >> they also say there was no reports of anybody resisting arrest. there were no reports of anyone being injured as well. >> this is now we come down to amsterdam i'm avenue to see all the police officers who are protecting it so that the buses bringing out the last few people who were arrested can get out. there are protesters behind us there are also on the other side of amsterdam avenue. this is interesting as well. so this is john j. hall just on the corner of one 14 and sudan. and you can see all the individuals hanging out there windows just watching what's going on out here hamilton hall is just up the street here other block. and that is now secured. there were reports that there was smoke off the top of hamilton hall earlier, police say that that's not true. there were people who claimed that they were using a tear gas kalisa that is not true. they did use flash bang grenades. they said when they went into hamilton hall, the doors were barricaded with tables, with chairs, with soda machines they use the flash bangs to distract whoever was in there. and then they were able to open up those doors and get get more officers in to clear out and check and then clear out the entire hall. but at this point, we're this start started around 9:00 p.m. it's done they the police will say the columbia's asked him as i heard you talking about until may 17, commencement is on may 15th. so they certainly want to have that presence what they don't want to have i'm happen is what happened last time, but they clear the encampment, they clear the protesters, and then they re-establish themselves the next day or the following day. so that's something that they are going to make sure it doesn't happen. john miguel mark has just sounds like columbia university were police say it's done the campus has been cleared. hamilton hall has been clear. the encampment has been cleared, no injuries. the police say much
