barbie, can you hear me? all right. okay. barbie, i think i've got you now. tell me, explain to me what's happening tonight. >> reporter: right now i'm standing in the epicenter of all of the violence we saw earlier. and really right now the protesters are gone, they've been carted away. but it's really a waste land. right in front of me is a burnt out police vehicle. there are cobblestones all over the place. there's so much broken class it's like walking on frozen snow. there's so much debris on the ground. the smell of tear gas in the air. many other protesters have been carted a eed away. lots of them have started trouble in new parts of rome. we have 70 confirmed injuries, 40 of which are police officers. 30 which are protesters that are confirmed injuries. there were a lot of other people who didn't seek hospitalization that were injured either by, you know, flying glass from these broken bottles and things like that. the situation is definitely calm now in rome. there's normal traffic, normal movement in the city. but there is, you know, an aftermath. lots of these streets that were the epicenter of the violence are closed now and probably won't be opened until monday. >> so is there any talk, barbie, that those who were organizing the peaceful protests, whether they resume taking to the streets tomorrow or the next day? >> reporter: well, there is right now. i heard italian media has reported that the peaceful protest will try again next week either thursday of friday. they have to get permission from the mayor of rome. but i heard the mayor of rome is is also standing here addressing some reporters saying he completely encouraged those protesters to get out again and have their voice heard and to not give into this anarchistic violence that hijacked today's peaceful protests. the people out on the street legitimately were overshadowed by the violence definitely. >> barbie, thank you so much from rome. a very different scene in london where thousands gathered near the heart of the city's financial district. unlike rome, the london protests remained peaceful. financial protests like this are going on in at least 82 countries rallying against corporate greed, grinding poverty, and government cuts. the global protests began last month in new york as occupy wall street. many of the protesters have been camped out in new york's financial district now for about a month. earlier today, they marched past a chase bank urging people who use big bnks to transfer their accounts to worker-owned banks. a rally in new york's time square is set is to begin in less than an hour from now. president obama is praising democrats and republicans for reaching a deal on free trade agreements. but in his weekly address to the nation, he expressed frustration that both sides are still so far apart on how to get americans back to work. >> it's good to see congress act in a bipartisan way on something that will help create jobs at a time when millions of americans are still out of work and need them now. but that's also why it was so disappointing to see senate republicans obstruct the american jobs act. even though a majority of senators voted yes to advance this jobs bill. we can't afford this lack of action. >> republicans on the other hand say the gop is actively engaged in jump-starting the economy. >> we agree with the american people. no more budget tricks, no more accounting gimmicks, no more broken promises. the american people deserve the right to know the truth. and that's why we support a balanced budget amendment to the constitution. >> and the president takes his jobs plan back on the road monday, a three-day bus tour through north carolina and virginia. tuesday night in las vegas is debate night here on cnn. one leading republican candidate won't be there, jon huntsman's beef with nevada next. a full serving of vegetables plus a full serving of fruit. but it just tastes like fruit. v8. what's your number?

>> well, certainly the roots of the civil rights movement. as we know when daddy started, there were already things happening. it wasn't -- the movement didn't start december 1st, 1955. in fact, that wasn't the first time someone had sat down on a bus and was mistreated. and so -- but the seeds of where people get tired of being trampled upon, being mistreated, i see those seeds of frustration being expressed. >> and tune in tomorrow in the 2:00 eastern hour for more of my interview with bernice king and martin luther king iii. and tuesday night is debate night in nevada. cnn hosts an evening of q & a with the loading republic ilead candidates for president. jon huntsman took nevada off his campaign calendar completely. the former utah governor is not happy with the state's decision the to move its gop caucus ahead of new hampshire's. huntsman says he made other plans for tuesday. >> so i say if you're going to boycott nevada, you boycott the debate. you do it straight up, you do it fully loaded, and so tuesday night, we're going to be here as we will be on monday campaigning and doing town hall meetings. and sharing our vision with the people of new hampshire and answering questions that people of new hampshire have about where this country needs to go. >> all right. live now to las vegas and our senior political editor mark preston. mark, jon huntsman is now the only candidate threatening to stay away from nevada. who else? >> reporter: welm, you're absolutely right, fred. there are four other candidates saying they will boycott the caucuses. we should be clear, this is a political calculation on his part. he had no chance of winning the nevada caucuses. he's going to put all his chips on the line and try to do that in new hampshire. he's trying to woo the voters in new hampshire. herman cain, newt gingrich, michele bauchmann, and rick santorum. four candidates who all have said they will boycott the nevada caucuses because the nevada caucuses are up against when new hampshire wants to hold their primary contest. in addition to that, though, fred. >> i'm sorry. go ahead. >> reporter: in addition to that, though, the question is, what is the nevada republican party doing out here? and i'll tell you what, they're staying by their guns, sticking by them. listen to what was said earlier on cnn today about their decision to keep the caucuses on the date of january 14th. >> we're going to stick to our date. our state is working hard on finding their locations. and we worked together with the states making sure we coordinated and communicated. the new hampshire gop has been fantastic, very supportive, it's the secretary of state who has the end say in the situation. but we reached out to him and he did not return our calls. we did have the governor talk to him, as well. and during that time, he still did not have a date picked. and he said he was going to wait on us. we did exactly that, picked a date. >> reporter: and there you have, the nevada republican party chairman talking about the secretary of state of new hampshire who has threatened to perhaps hold his primary now in december, fred, if you can believe that. >> wow, that is hard to believe. i don't know if some of these candidates are -- they're concerned about these caucuses and primaries being moved up if they're wondering whether that will kind of deviate in their finances if they can campaign heavily enough for some of these locations earlier than they originally expected. is that part of the problem? >> reporter: it certainly is a problem. and we're also talking about the holiday season and new year's. you know, if december is the date that new hampshire holds its primary, it will throw the whole political calendar on its head. but even if new hampshire does hold its primary on january 10th as a lot of people are hoping it does so, it still will have iowa hold the first in the nation nominating contest. their caucus on january 3rd. it means there's no christmas for these candidates and it means the voters out in iowa and new hampshire perhaps even nevada are going to have to see these candidates at a time when they would probably prefer spending that time with their families. >> okay. mark preston, we will see how it all unfolds, won't we? be sure to tune in first this tuesday for the cnn western republican presidential debate coming up tuesday night, 8:00 eastern time from las vegas, cnn's anderson cooper will be the moderator. how about this question?

that's a subject of our weekly look at how to get and stay healthy. dr. bill lloyd, our healthy living expert joining us from san francisco. good to see you. we would never break up, not here. so, doctor, what are some reasons that patients say, you know what? i don't know if this is a good relationship, i want out. >> well, fredericka, the relationship between patient and doctor is somewhere between the relationship you have with your hairdresser and your barber and a marriage. so good haircuts and bad, sickness and health, but nobody said until death do you part. and we should be able to feel free to change our health care providers. and these are some of the most common reasons. first involves poor communications, particularly at the -- doctors typically will not let a patient talk more than 13 seconds before they interrupt. patients often have times with the staff in the clinics. the doctor may not be a problem, but the people working in the clinic may make it miserable for them. doctors may be too busy, takes too long to get an appointment. you wait too long to see the doctor for what? four minutes? some people get aggravated by that. there can be a personality conflict. the doctor may, in fact, be a know it all. and you know how irritating know it alls are to those of us who do, fredericka. and patients want to break up because of quality of care. and that is so low on the list. most of the time if they like their doctor, they're going to forgive their doctor if there's been a mistake. >> then say you do want to break up. how do you do that? some might feel intimidated by their doctor. how do you go about doing that? >> excellent point, you know, 20 years ago it was a big deal if you left your doctor. but with managed care now and portable medicine, people are changing for all kinds of reasons. and sometimes the doctors don't even know where their patients went. if you think you want to leave your doctor, though, give it 24 hours, talk to some family members. you may find out it's one of the reasons on the list we just talked about that really doesn't have anything to do with the doctor. and if by communicating with the doctor what the real problem is, whether it's parking or appointments or whatever, there may be a fixable problem. for example, if you have your appointment every thursday afternoon, you may find out tuesdays are wide open and not a problem at all. so you have to take some responsibility in that part too. before you pull the pin, talk to the doctor and see if there are any fixable problems. >> and i guess, aren't there usually warning signs? maybe it bubbles up over time. what are some of those warning signs you need to pay attention and act on those instincts? >> well, if there's trouble with access, you can't get returns to phone calls, even having trouble getting an appointment. you might consider going elsewhere. why is he recommending surgery all the time? i don't think i need surgery. if you can't get a clean answer, go ask the questions of somebody else. any time you feel ignored, like your statements don't mean anything or the doctor's very dismissive of your ideas, that's no partnership. good health requires a partnership between the patient and the physician and a doctor who fails to explain anything regarding any therapy, risks, benefits, and alternatives. if you're not getting the information you need, you can't make good health care decisions. >> is there a way to simplify the transition? maybe you're in the middle of treatment or changing medications, etc. but you don't want to put your life in jeopardy, your health in jeopardy while you're transitioning? >> well, you're right, and that can really weigh on you. if the first thing you want to do if you're going to make the change is find the new doctor first. make sure there's one that's as good as the doctor you're seeing right now. you don't want to cut the cord if you don't have a good doctor. check with your insurance company to make sure that new provider is going to be eligible for you. make sure you take care of the arrangements for transferring of records. you need to sign a patient release. you can do that by going into the clinic office any day. but before you finally walk out, though, you probably should have a conversation with the doctor. don't send them a text. have a conversation with the doctor. explain what you feel the issues are and why you feel the need to move on. and don't feel guilty. >> all right. dr. bill lloyd, always great advice, thanks so much. >> we'll talk again soon. >> all right, thank you. still to come, hip hop's business is booming, but will its economic success lead to its artistic down fall? the son of u.s.-born militant cleric al-alwalki is dead. two weeks ago, a key member of al qaeda in the arabian peninsula was killed in a drone strike. a meaningless and absurd accusation, that's what iran's supreme leader calls america's claim that his country plotted to assassinate a saudi diplomat in washington. he made the comments today. he says the u.s. wants to isolate iran from the rest of the world. but u.s. authorities insist the allegations are true. they point fingers at the quds force, an elite special ops group that reports to them. >> elise, so far, is there anyone within the iranian government that's being implicated? >> not yet. basically what the administration is doing is implicating senior levels of the quds force, this force that's part of the irgc. but not really saying right now who in the iranian government knew about the plot. >> is it possible that this plot could be planned and not involve or without the knowledge of ahmadinejad or khameini. >> basically the obama administration for the last year has been pointing the finger at this quds force and the irgc as really running a lot of the oir economy and military, there are many power centers in iran. so basically what -- it hasn't been hurt that much by the arab spring. and it doesn't seem as if the iranian government, president ahmadinejad, or the supreme leader would have any reason. it's very possible these are freelancers here. >> there are some analysts who say this doesn't even fit quds force, that usually they do things with precision and this exemplifies a sloppier operation and that it wouldn't involve a muslim extremist is odd that it would instead involve a mexican cartel. >> that's very true, fred. i mean, the quds force is one of the most organized, precise military arms of the iranian military and the irgc. and it just doesn't fit the profile. a lot of times they use proxies like hezbollah, like hamas, and it just doesn't fit the profile of the quds force. >> what's next for the u.s.? >> well, already the united states is making its case to the international community, the state department has brought in all of the diplomatic core to brief them, calling members of the u.n. security council, and they're already moving ahead talking to committee, senate banking committee to talk about possible sanctions. they've sanctioned several individuals. so they're moving ahead. whether they're going to take dramatic action against the iranian government, unclear because we don't know necessarily who was responsible, but certainly they're going after the quds force and the irgc. >> elise, thanks so much. the u.s. is accusing a texas used car salesman of ordering the hit on the saudi ambassador. he is an iranian-american who is expected to plead not guilty at a formal hearing later on this month. legal trouble for an american catholic bishop. we'll look at why he's under indictment and what it could mean for
