All day today people here have been paying their respects to the people in orlando. Also reassurance from police that theyre doing all they can to prevent a similar tragedy from happening here at home. Reporter at 18th and castro, a crazed gunman targeting a gay nightclub thousands of miles away hits very close to home. When is this going to stop . When are we going to wake up and realize we need to address the gun violence, address the access to the guns to do this . Reporter when word of the orlando shooting got out, people in decastro started dropping off candles, flowers, even writing hopeful messages. Hence my sign over there. It says love all, dont hate. Reporter but hate could happen anywhere, says supervisor david campos who has his own concerns. Its a fear. I think in the minds of everyone that ive spoken to. We need extra security during the pride parade. Reporter San Francisco police say starting today they had increased Police Patrols in decastro and other crowded areas. We hope our presence down here reminds them this is a very safe and wonderful neighborhood and they should enjoy the day. Reporter police say theyre already working with federal Law Enforcement to ensure that pride 2016 is both safe and fun, which is exactly what some in decastro say it should be. We need to take the action of going out and demonstrating that this doesnt stop us. We unite because of it. The supervisor scott wieners office is organizing a vigil happening behind me, harvey melk plaza. He says it will be a time to mourn but also to recommit to the fight for lgbt equality. Mark kelly, kpix 5. Today is the Big Pride Party in west hollywood. Hours before the parade started, Police Arrested a heavily armed man who told them he wanted to do harm to the pride parade. Police were called this morning about a prowler in santa monica and the man they arrested, 20yearold james howell had multiple weapons including one Assault Rifle and chemicals used to make explosives. The parade went ahead as planned. I want to thank Santa Monica Police department for their good work and the tip that led to that arrestment i want everyone here to know that we are safe, we are protected, our Law Enforcement officials are here. The man arrested is from indiana. Right now police say theres no connection between the suspect and the man behind the orlando massacre. We should mention this is also the first week of ramadan. Some jihadist groups like isis use ramadan to stage brutal attacks. Retired fbi agent and kpix security analyst jeff harp joins us. There have been questions about why the police didnt enter the club sooner to try to stop him from doing what he did. Theres a lot of armchair quarterbacking and hindsight 20 20 things that will happen. When they show up on scene, they have to address the situation. Officer safety, to the public, so they also, not knowing whether orlando has a fulltime s. W. A. T. Team or not, theres people showing up on scene. Youve got sheriffs deputies, city police, various agencies showing up. They have to come together and have a plan. You dont just automatically rin in and do something. You dont want a blue on blue situation either where you have officers shooting at each other. They have to assess it. It takes time. It also takes time to get all the equipment there. If they had an Armored Vehicle they wanted to ram the wall with, if that truck is not on scene, it takes time to get that truck from where the staging location is to the scene. These things evolve. They dont always evolve as quickly as people would like to see them evolve but theres a set plan to put in to place. They probably need to know also what the layout of the club is like and where the gunman could be. In a best Case Scenario theyre going to get blue prints to whoever has access to the club. Theyll interview people as theyre coming out. Theyll ask them where do you think the shooter is . These are quick questions that are asked, very specifically. So they can put their plan together. Their emergency assault plan together very quickly. The fbi investigated the shooter before. Hed come under surveillance, some kind of an investigation several times in the past four years. And i think the question tonight is first, how many people like this do the fbi investigate and say, gee, this guy is raising some red flags . And how could somebody like this whos come under suspicion before secure guns legally . The process that the fbi goes through to clear somebody or to say they dont pose a threat, just because youre under investigation by the fbi, we certainly dont want the fbi to keep a list of everybody they talk to then use that list at some point, i think we got away from that long ago in the Jay Edgar Hoover era. So what theyre trying to do, theyre looking at this person, theyll make a determination based off of an interview. They dont have a search warrant. They dont have an arrest warrant. This is basically a threat assessment thats done. They go out and talk to the guy. If the guy decides to cooperate, thats great. But the guy is only going to volunteer what he feels he needs to volunteer. Hes not going to say yeah, im a terrorist, its time to arrest me. Theyll use whatever tools they have by law to do the threat assessment. Theyre simply going out there and talking to this guy. If its based on a tip, if its based on i believe the coworker had said he had spouted some hate and discontent toward either some groups or other things hed said, but the fbi is going to talk to him and theyre going to do what they have to do to get the investigation moved down the road. If they find theres nothing there to say hes involved in terrorist activities, theyll close that. Just by virtue of the fact the fbi has talked to him, it doesnt mean the name is bounced off a list for being able to get a gun. If he came under the fbis radar, before theyll go out and talk to the guy. Theyll do all their checks. Does he have any registered weapons . Who is he associated with . If hes not associated with anybody and if hes just exercising his First Amendment right, freedom of speech cant do anything. Right. We live in america. Youre allowed to say what you want to say. Certainly we want the fbi to operate within the parameters theyre legally allowed to do so. Well be learning a lot more. The days and weeks to come theres going to be a lot more that we learn. Kpix 5 security analyst. Hillary clinton and donald trump both took to social media to express their condolences but donald trump repeated his call to ban muslims from the u. S. Trump tweeted if we do not get tough and smart real fast, were not going to have a country anymore. Because our leaders are weak, i said this was going to happen and it is only going to get worse. Im trying to save lives and prevent the next terrorist attack. We cant afford to be politically correct anymore. He didnt mention the gunman was born in the u. S. Hillary clinton also released a statement. Part of it reads this was an act of terrorism. For now we can say for sure we have to redouble our efforts to defend our country of these threats here and abroad. Were learning more about the nightclub itself. One of the owners says pulse was open to promote lgbt awareness. It also serves as a tribute to her brother who died from a. I. D. S. Barbara says the name of the club signifies her brothers heartbeat and where he can be kept alive. Coming up, well have up to the minute coverage at cbssf.

Students brought signs in to the stadium today and there was also a big banner carried by a plane that was circling almost continuously overhead. While overall there was just a relatively few number of students who actively took part in the protest, their anger and frustration with the case, the campus, the judge, and judicial system were at large. Reporter the message was unmistakable. Standing in stark contrast to the celebratory and often downright silly mood of a graduation ceremony. They dont think rape happens at stanford but it does. It happens more than we think it does. Reporter stanford has landed in the center of a nationwide debate over campus sexual assault. After one time olympic hopeful brock turners sixmonth jail sentence for assaulting a woman who passed out drunk at a Fraternity Party last year ignited a social media firestorm. We need to be doing more as a society to teach young men not to rape people. Reporter he said much more needs to be done to reduce Sexual Violence on campus. Theres an element of you got accepted to a school like stanford and you shouldnt be doing this to people. This should be something incongruent to your character if youre a stanford student. Reporter protesters hired a plane to fly over the stadium that said protect survivors, not rapists, a message aimed directly at judge persky, who presided over the case. This is not the venue to make a statement. Reporter not everyone agreed. Rape is a criminal matter and stanford appropriately turned the whole thing over to the police for investigation. Reporter like it or not, the disappointment with the turner case was on display today for all to see. Keynote speaker ken burns also made brief mention of the brock turner case today. He said he has four daughters himself and if someone says they have been sexually assaulted, thats something you have to listen to and take seriously. Devin fehely, kpix 5.

You might be able to see behind me this is still a very active scene. You can see people standing up where those cars are. A lot of people are just kind of coming out.

Wrapping around buildings. So much that the blood banks have said try a different one, we have too many people. A lot coming out saying they want to help. They feel like they want to stand as one orlando. They need to stand together not just for their city but for the lgbt community. A lot of people having a hard time wrapping their minds around the fact that 50 people were killed in a nightclub, that people were just having a good time for the evening. 53 people injured. The names are still trickling out. So there are a lot of people here waiting on pins and needles, hoping their friend or Family Member isnt the next name released. We understand the city of orlando is trying to help victims loved ones get information and that the city is beginning to post the names of the People Killed on its website . Thats right. They initially told people if you think you know somebody, or you cant get in touch with your loved one, come to the hospital and we can figure something out. Now theyre asking people please log on to the citys website. You can give us information there. Only seven names have been released out of the 50 killed so far. This information is coming out very slowly. But this is the deadliest terror attack since 9 11, the deadliest mass shooting in our nations history. 53 people were killed. Its going to be difficult to get all the people identified. Its going to be difficult to find their Family Members and you cant release the names till you do that.
