> republican presidential hopefuls gear up for another debate. things on stage is getting ugly, it's nothing compared to spectators at donald trump's event. nasty words and fists flying. david shuster reports. >> get them the hell out of here, will you. >> reporter: after the angry words of donald trump, there's evidence of angry deeds by his fans. the latest wednesday in north carolina. on the right watch the man with the red sleeves, brown hat and pony tale. following a sucker punch, police handcuffed and removed the african-american protestor who within hit. >> you ain't got to grab him like that. >> reporter: police charged the attacker with assault.

an unapologetic man, john mcgraw. >> he deserved it? >> every bit of it. >> reporter: what was that. >> yes, he deserved it. the next time we see him, we might have to kill him. >> reporter: the episode is the latest trump even marred by violence. trump the front runner is not quick to criticize the as. >> if you see someone ready to throw a tomato, knock the crap out of him. you see them walking out laughing, smiling, i'd like to punch them in the face. >> reporter: critics say donald trump is out of line.

>> raise your right hand. >> reporter: it is said that it helps the security recognise trouble makers. the pledge mirrors a nazi salute and is offensive obnoxious. at the white house president obama fired back at republicans that argued his administration fuelled trump's rise. >> i have been blamed by the republicans for a lot of things, but being blamed by their primaries and who they are selecting for their party is novel. >> reporter: as the republican identity crisis drags, democratic presidential candidates sparred with words in wednesday night's debate. >> there is a reason why wall street has provided $15 billion

in the last reporting period for the secretary's super package. >> it's worth pointing out that the leaders of the fossil fuel industry, the koch brothers, have paid to put up an ad praising bernie sanders. . >> it's true they released an ad, but praises the export-import bank, not fossil fuels. clinton was pressed on controversial emails. >> if you get indicted. >> for goodness... it's not going to happen i'm not answering that. >> but clinton and sanders hope to answer questions on donald trump. >> his rhetoric is dema goingary, his trafficking in paranoia has no place in our political system. >> i think the american people are never going to elect a president who insults mech cans,

who -- mexicans, who insults muslims, who insults women. >> reporter: maybe so, but the republican party is on track to select trump as their nominee, and for better or worse, the determination of his supporters seems to intensify. michael shure is in miami with a preview of the presidential debate. "the washington post" says ben carson is going to endorse trump. it seems to get stranger by the moment. >> it does, and after listening to david shuster's report, it may come at the right moment for donald trump to build themselves as the moral center of the party, even though it didn't take him far in the election in terms of votes. that is sort of the way that ben carson has been able to identify himself to the party, and that

is something that donald trump will need. it may not bring with it a lot of votes and support, it brings with him a little moral support na donald trump needs from that part of the party. when you hear ben carson do that for donald trump, it is surprising that he is endorsing everyone. you knew ted cruz was not going to get it. still a bad taste in the mouth. that was not going to place for the conservative ben carson to go. >> we have seen fireworks at g.o.p. debates before. what do you expect tonight? >> i think you'll hear a little of the sax. rubio is rethinking his strategy going after donald trump, trying to stay in the race, going after florida. trump is saying it doesn't matter, that will not be a big factor. ted cruz will try to sell himself as the only her honour that can defeat donald trump, he wants nothing more than this to

be a two horse race. >> what about issues that have been weighed in on lately, comments about islam, and the fights that have gone on at some of his rallies. >> any other time in our history i don't need to tell you this. they would disqualify a candidate right away. he would never have seen this happen without recourse. it is happening, it happens weakly and has not affected his base. they don't care about it, they get excited about it. as you heard in david shuster's report. they talked about donald trump, hillary clinton calling him american, and bernie sanders shocked at the way he talks about other americans. there is a ceiling, donald trump has not crossed it. but he keeps on winning. >> ted cruz comes into the debate picking up an endorse: maybe overshadowed by donald

trump's endorsement. >> it is important for ted cruz to get mike lee. most don't know who he is. the junior senator from utah, but it takes away an argument that donald trump made the time, this guy works with 99 other people, not one endorsed him. well one has, and that's better than none. >> michael shure, thank you. >> unity within the republican party is important. i believe we have a rare opportunity right now. i believe unity is more possible than ever before in this race. we need to unite behind ted cruz. >> and, you know, that is mike lee endorsing donald trump today. again, it is important, because it changes the way ted cruz can be attacked. most people know ben carson, most know mike lee. it's a subtle importance for him. >> i'm glad you are pointing out the subtle ties michael.

good to see you, thank you very much. there's a reason the debate is in florida, the state holds its primary on tuesday, it's a big prize in the election season. adam may is in melbourne, florida, part of the state that g.o.p. candidates will be watching very closely. >> good evening, we are in berbard county, a barometer for the g.o.p. during the last three decades republican voters here picked a candidate that goes on to win the g.o.p. nomination. >> what is happening this year? yes, marco rubio trailling in the florida polls. in this county he is leading when it comes to fundraising, if those dollars don't translate into votes, the run for the white house could be in big trouble. >> reporter: barbarb county on the central east coast is on the

republican radar, for the past 30 years, when g.o.p. voters leave the beach to pick the presidential candidate. the winner gets the parties nomination. >> why do you think barbarb country has a history of picking the winner. >> i would think there was military reminded people, people that believe in their country and the exploration of space. people that are really the core and that's what we are really fighting for now, is the sole of the republican party. >> i'm helping marco rubio. >> jason steele is a former republican chairman and a marco rubio supporter. the florida senator needs a win in their home state. polls show them trailling donald trump, still believing the county could be a place where marco rubio shakes up the race.

>> the county has a far right. there are people that are to hell with everyone. then there's the good conservative people. they have been the majority here. >> what are the issues that the voters care most about? >> the biggest issue is the space industry, the exploration of space. >> reporter: the space industry took a hit in 2001 when n.a.s.a.'s shuttle programme at cape canaveral ended and thousands lost their jobs. by november 2012, the mostly white middle class population with a hardy number of military veterans saw the highest

foreclosure rate in the nation. >> we can't have a robust economy without honesty. the way that lending is set up. the way that business is set up, the way that a free market works requires honesty. >> richard webb is a realtor in ber barb county and believes that republicans here are moving away from establishment politicians, which could be good for cruz or donald trump. >> they have been disappointed in several elections with people that said they'd clean it up, and didn't. now there's an animosity that has grown, they are the trumps that you are talking about. >> bill faden is a trumpster, a small business boner that --

business owner that decked out this area. >> this guy looks like he can do it. professional politicians will lose their job, there's not a lot of use for people in the republican party. >> marco rubio is hitting florida hard. supporters fighting the "e" word, establishment. >> place de la republique has been an underdog. >> reporter: he is hoping for an upset, a win, and the bod luck that comes with a victory. into talking to voters, they are tuned into the issues and are

able toive. the county is leading when it comes to early voting. 17" have cast their ballots. including republicans that made up their mind. >> sabrina is a reporter with the guardian. what are your readers saying about the race going on in the united states for president? >> there's a lot of fascination with the rise of donald trump. he's an selected member of congress, bernie sanders, but outsiders that dominate the direction of the race. it speaks to the frustration playing out on the ground. not just in one country, but across the country.

>> what do they say about the tone of the political conversation between the candidate and the voters? >> on the republican side it's been striking because donald trump any given day said something that tests the boundaries and limits of what is said in the history of any presidential campaign in the united states. it's remarkable to a lot of people that he gets away with one controversy after the other. it seems to blunt his rhetoric. >> there has been talk of a germ debate, do you believe that? marco rubio had gone very aggressively after trump your in recent weeks. >> it's a strategy costing when

it dove into personal attacks. he regrets having done it. he said that for the first time. kids were embarrassed by it. we'll see an effort by candidates to steer clear of the gutter politics that donald trump is known to traffic in. you'll see attacks on donald trump's preparedness to be president. those are point that his rivals feel are important to try to make. so republican voters under who they are on the verge of nominating. >> let me talk about the democrats. what is the biggest contrast in your mind? >> it's interesting in recent weeks. and watching how hillary clinton went from making the argument that bernie sanders is not rude in reality, to trying to make the case in a recent debate that was held.

he's not exactly as liberal as he prefers to be. he's a fair weather liberal, she the case on gun control, on the autobill. that he's been a strange bedfellow with republicans, i don't thick that anyone will buy it in a primary. because bernie sanders had a progressive record. it could be a mistake, because it certainly comes off as disingenuous. perhaps hillary clinton - there's a team thought that they need to come with a new line of attack. electability argument not working with either party. >> could you give us colour of what you have seen and heard in anticipation of what might be said? >> i think that ted cruz wants to define this has a 2-man race. even donald trump does. the goal is to edge marco rubio out of the race. you'll see an effort by trump

and cruz to define it as a contest moving forward between the two of them. ted cruz is going to make the case that he is the only candidate that has beat donald trump in frame rice and caucuses. even if not overwhelmingly so. there is truth to the statement. john kasich is a factor. he's going into an important winner takes all contest, playing the role of adults, sticking to policy, and you'll see marco rubio stick to policy. that lid to success where he came off presidential - i would anticipate that he wants to present himself as a serious commander in chief. and steer clear of too many things that could harm him we'll see if they stick to policy. great to see you, thank you very much. >> the white house rolled out the red carpet for canadian

prime minister justin trudeau. the first official u.s. visit by a canadian leader in 19 years. president obama hosting a state dinner for justin trudeau. the visit is a sign of the warming relationship between the u.s. and its northern neighbour, the thaw has been a long type of coming. >> good evening, for president obama and prime minister justin trudeau, it's been a day marked by goodwill and agreement on areas of mutual concern, like the environment. both hoping that it marks a new chastors in relationships -- chapter of relationships within the two countries. >> reporter: it's been two counties confirming a deep bond with the ceremony of a state vist. >> we are proud to welcome the first official visit by a canadian prime minister in

20 years. it's about time, hey. >> reporter: the shadow of the primary hung over the visit. with prime minister justin trudeau looked on. president obama arrived if he was in part responsible for the political tone, calling the republican race a circus and a crack up. mr obama says the party has nothing but itself to blame. >> what you see within the republican party is those efforts over a course of time creating an environment where someone like a donald trump can thrive. >> reporter: justin trudeau, jokingly suggested that americans opposed to donald trump could take refuge in canada, trying to stay above the fray. >> the relationship and friendship between the two countries goes beyond two individuals or ideologies.

>> reporter: obama and the relationship of justin trudeau, the son ever a prime minister that took office in november. the leaders announced a pack to cut oil and gas methane emissions by 40-45% by 2025 and pledged new agreements with the arctic. the process to implementation the the deal on the u.s. side will last beyond president obama's time in office. it will be up to his successor to follow through - or not. u.s.-canada's relationships was strained under stephen harper, who pushed the white house to approve the keystone pipeline. obama ultimately rejected that plan. he has a canadian partner working towards a clean growth economy. >> i'm confident that by working together we'll get there sooner than we think. >> in praising u.s. ally and neighbour canada, it almost

sounded as if mr obama were talking about justin trudeau himself. >> we see ourselves in each other. we are guided by the same values. >> there's an agreement to open the borders. more than $2 billion in goods and services demros. -- flows. this would open up the boarder, breaking up bottle necks, allowing trade to flow freely. canada is moving ahead with plans to build a bridge. it will replace one that connects cities of windsor and detroit. facilitating $200 billion in trade. plans on the american side have not been finalised. bisi onile-ere reports the detroit-windsor corridor is the busiest international trade crossing in north america, suspended over the detroit river, the ambassador bridge

connecting canada to the u.s. in 1929. the bridge's billionaire owner matty maroon tried to get permission to build a second span. at the same time fighting canada's plan to build a government-owned bridge nearby. named after a hockey legend, the new bridge expected to cost more than $4 billion will be funded by the canadian government. >> to have a new crossing is a positive statement for south-east michigan. >> reporter: the business professor says more than a quarter of the $7 billion trade between the two countries crosses here. >> for canada trade with the u.s. is critical. it's a life line, it's their biggest export market, of course. it's critical to the economy. >> during his visit to washington. justin trudeau addressed the significance of international

trade. >> the president and i acknowledge the fundamental unique economic relationship between canada and the united states. we have historically been each other's trading partners. each and every day $2.4 billion of goods and services across the boarder. we reaffirmed today our commitments to streamlining trade. >> the gordie howe bridge will be built two miles south of the ageing ambassador bridge. the new structure will slice through detroit's del ray neighbourho neighbourhood. activists are concerned about the impact that it will have on the poor area. >> we said yes, we want a seat at the table. >> reporter: some residents have been paid to move. they are pushing for the u.s.

and canada to provide more support. >> i have been critical of canada. this is their most important transportation project. they spent i think over $2 million on community benefits for windsor residents, making sure they have green spaces. i hope they treat us equally on the american side. >> reporter: in the meantime construction is in the early stages in canada. the country will begin to recruit its investment and revenue when the bridge opens in four years. and coming up next on the broadcast - flooding in louisiana forces thousands from their homes. a look at how long the weather disaster is ready to ask. >> the senate committee digs in to the fight to prevent president obama filling a

supreme court vaguansy -- vacancy.

prosecutors in pennsylvania say two gunmen were on the run after shooting five people. four women and a man. one of the women was pregnant. that'll be another homicide. one gunman fired a gun to drive victims towards a second gunman weighing with an assault-styled rifle. rain fall in the south, adding to the flooding and misery that's affected the region, part of louisiana under a state of emergency, and the flooding may be far from over. jonathan martin is in new orleans. >> reporter: from louisiana to texas to tennessee. much of the south is under several feet of water after days of heavy rain, and forecasters say the rain may not let up

until this weekend. north-western louisiana was one of the hardest hit places. drones show water inundating neighbourhoods near shreveport. thousands told too leave their homes. those that stayed had to use boats to get around. >> roadways are flooded. you can't see the signage, feeling your way through the water. >> torrents of water swept cars and trucks off highways. the national guard was called up to help residents. in texas firefighters rescued a family. across the region dozens of people and animals had to be rescued. >> this is an event that sneaks up. it's one of those that you are not proactive for, you become reactive to it. rain sent streams and rivers flowing over their banks.

>> in louisiana, fish from seen swimming in the streets. in tennessee rain caused this landslide in memphis. with roads in the south flooding. in some places the schools closed. communities are trying to keep the water at bay. people are doing their best to cope. it could be several days before the region drives out. >> next, donald trump's planned rally in chicago. how he is expected to be received in the democratic stronghold. and the nonprofit health clinic at the forefront of the fight against the zika virus in texas.

>> our american story is written everyday. it's not always pretty,

but it's real... and we show you like no-one else can. this is our american story. this is america tonight. republican donald trump will hold a rally tomorrow in chicago. >> reporter: carlo is a chicago business owner like donald trump. the restaurant sits a few blocks from donald trump tower. last week he snapped up free tickets, now he can't wait to go, or can he. the idea was to get as many of the tickets as he can, and not go to the rally ideally to make it look like there's only 30 people there in a fairly blue disat chicago is a -- state, chicago is a blue city. donald trump is a distant third

in their poll behind rivals john kasich, and senator ted cruz. in part is this cute. it's our goal to say this ain't the neighbourhood. a stage is being set up across the street to handle protesters. this uic student is one of them. why uic of all places. the second reaction is anger. the campus is as culturally diverse as anywhere in the country. the group is relishing the chance to take aim at donald trump. this is a chance to empower ourselves and speak up for ourselves. 200 teachers signed a letter to the school of administration, urging them to cancel trump's

rally over fierce of violence. they farmed is stop trump social media site to coordinate the protesters. >> that would put as answer outside the pav illion as can pit inside. uic takes no position whatsoever on donald trump, but is renting out its pavillion as it would to anyone that pays. donald trump supporter sandy also got a ticket to the rally. and she will be going. >> is it lonely being a trump supporter in a blue state? >> yes, it is. it takes guts to come here, i don't know how well perceived it will be. this is why we have the first amendment. everyone has an opinion. protesters voice theirs, we ours. >> this congressman, also protesting at the rally says the demonstrators will not make a big of difference to trump

supporters or detractors, but says that is not the point. >> i think it is important that when history is recorded, his trip to chicago did not go buy with our silence. silence is acquiescence to his message. >> donald trump is not backing away from controversy, or his fiery rhetoric. here is what he said about islam on cnn. >> i think islam hates us. there's something there that - there's a tremendous hatred there. we have to get to the bottom of it. we have to be very village n lent. careful. we can't allow people coming in to this country with this hate red of the united states, and people that are not muslim. >> lenny macauizester is a cove commentator and former congressional candidate.

do you belief it's an off the cuff comment or did he plan to say this? >> this is part of his rhetoric. number one build the wall, number two mexico will pay for it, and number 3 we are not safe because of islamic terrorists because of people coming here, people that are different, threatening jobs and livelihoods. that is something he's said since announcing his running for the candidacy. he's trying to seal the deal. trying to make sure they vote for him. looks like he walks up to the line, crosses it, and backpedals the next day. and says no, no, no, you got me wrong. what is the point of you will that. >> he's been getting away with it. he's been able to walk up to the line, quote unquote tell it like it is. basically do the dog whistling and walk it back and it's not quite what it meant.

from there he can spin it, have the team spin it and go from there. everyone knows what he's been trying to say, we've been doing it for years, since last summer, all the way flow, it's enough of a dog whistle getting people on board. trying to walk it back. hoping the media gives him an opportunity, it gives him a lot of free media, pick up the phone and go on five networks between 6:00a.m. and 5:00a.m. it's free media, he does not have to raise money, the media did his work. >> but, i mean, is it the same thing when he doesn't disavow the former head of a k.k.k. in the states, david duke, and then the next day says no, i disavowed him. is he trying to get people that are racist in this country to join his campaign. >> it's a dog whistle. he's trying to get people that

are scared. people that are on the fence in the campaign. going back to the silent majority. that is a dog whistle statement from the 1968 campaign, of richard nixon, during the turbulent '60s, mixen went to the -- nixon went to the folks saying there was a majority that didn't like the upheaval. they are the folks we want to bring on board. there's a reason donald trump took that theme from 1968, and was using it again last summer. he's trying to get people to come in and allow him to move to a nomination. unfortunately he is taking the worst of politics any means necessary, and applying it to everything that he has said during the campaign trail. >> some of this is getting out of hand. it's not just words. a trump supporter faces charges after punching a protestor at a trump rally. you can see it there.

and we've had reporters who have been mann handled. photographs have been mann handled. protesters who have been taken, as donald trump said "taken down", and he seems to rev up the crowd against these people. i mean, again, this - you believe this lights a fire under his supporters. makes them feel good? >> when you feel like you are a victim, and you've been victimized and you feel like you need to take a sense of vengeance and you see someone that will stand up for you, absolutely, it excites people. this is what i say about the evangelicals. vengeance is mine says the lord, not donald trump, not the united states of america, and not the victimized voter.

these folks are excited doing things that are the antithesis of what they purport in their daily lives and exit polls. i am not surprised. the people feel victimized. unfortunately, it's the wrong champion, this is not someone that is presidential, it's someone that is a bully trying to run for the president. >> you believe donald trump has taken evangelicals away from ted cruz. >> he has taken reported evangelicals. i would say to you these are people that basically identify themselves as evangelicals. it doesn't matter what label they use, if they don't vote with the faith, especially a guy asking god for forgiveness, if they don't vote with their faith, unfortunately what you have seen in the south is folks that should have gone to ted cruz have gone to donald trump, starting in south carolina. let's talk about primaries

coming up next like, florida and ohio. so tonight is the last debate before the primaries, the last republican debate before the primaries, does trump have to not make mistakes tonight. is that what he has to do? >> for a guy that seemingly can't make a mistake, basically he has to go in there and try to not really - i don't know how much he can not step in it. he's constantly doing that. it's his brand, how he's been willing. what he has to be mindful of is whether or not marco rubio can look inspirational and optimistic, whether john kasich can be the adult in the room. donald trump has to look like an adult in the room, versus the adolescent. if he's capable of looking like john kasich, he'll edge away the lead that john kasich has in ohio. he better hope that marco rubio

doesn't sound like a guy in 2010, now that he is doing the debate in miami, and has to put it out there tonight. >> are you surprised that ben carson is going to endorse donald trump? >> i'm saddened that ben carson is endorsing donald trump? >> why. >> he's the antithesis of donald trump. he was the humble guy while donald trump was egotistical. he was a quite calm guys, donald trump was a guy yelling at you. to see that guy get behind the bully, it doesn't seem right. we are in bisaro land. >> we'll see how much more bizarre it gets. president obama interviewing candidates to fill vacancies on the supreme court. state department says it will not consider any nominee offered up. top ranking republicans and

democrats fought it out with the judiciary committee. >> it's impossible to sort out the election ear politics from the fight over a supreme court nominee. republicans are repeating a stance that they will not vote against a pick from obama, they will not let that person come up for a hearing. >> reporter: entrenched positions. republicans say no supreme court nominee until there's a new president. >> we are not going to drop any nominee into an election year cauldron. i'm not going to let it happen to the good peep. people of iowa. >> democrats say it's fair to consider president obama's choice. >> i'm appealing to the better angels of your nature. when there's a nominee, do as we have done in the past, give the nominee careful consideration. meet with the nominee, ask the nominee questions. anthony thurston's business

meeting turned formal. no changes in the division between the republicans and democrats. the committee has the power to screen, block or ignore the president's nominee. >> the work of this committee will be shame fully incomplete if the committee refuses to do the important job of weighing a supreme court nomination. we were given a job to do, a job the american people want us to do. and the chairman of this committee is saying for the next year the committee will not do its job. >> president obama used his appearance with the canadian prime minister to urge republicans to consider the choice. >> i'm confident whomever i select among fair-minded people will be viewed as a qualified person. and it will be up to senate republicans to decide whether

they wanted to follow the constitution. >> the white house said the president was making progress, and washington news outlets report that interviews had begun. >> among those getting contention. shree, jackson, a d.c. based judge, who would be the first african-american woman to sit on the court. and jane kelly from the home state of judiciary chairman chuck grassley. >> we are seeing reports from the white house, the election process guarded by political calculation of what they thing will extert the most political pressure on me. >> republican lindsay graham admitted frustration, but said that will not stop him siding with the colleagues. >> we are setting a president here today. republicans are. >> in the last year.

at least of a lame duck. i would say there is a four year term. that you are not going to fill the vacancy of a supreme court. the president could announce the nominee. as spring comes to the capital there are no signs of a bipartisan thaw any time soon. president obama said today that republicans are betraying the constitutional principals if they won't hold a hearing. that's because of an electioneering politics. >> thank you. >> coming up next. how the state taxes is fighting the zika virus.

texas confirmed 19 cases of zika virus contracted oversees, as the mosquito season gets started, that could change. heath clinics are preparing for a rash of cases especially among the poor, hispanic residents. heidi zhou-castro has the zori. >> reporter: in dallas texas this mother is keeping a close eye on news about the jeepa virus. >> it travels, because the mothers get it and passes it to the babies without noing. >> it is sad. >> the greatest concern is in low income neighbourhoods where stagnant water is common. here in texas, the front line of

zika defense looks like this. clinic serve patients that are poor, uninsured and ties to countries experiencing the worst out breaks. apart from territories, the united states has not seen a case of locally transmitted zika. 32 states reported cases transmitted through travel. and texas has seen 19 cases, including one from sexual transmission. the director of the dallas county health department fears mosquitos are carrying the virus in dallas. >> the human is bitten in south america comes back to the united states and now has symptoms bitten by mosquitos, it local lies victims. it will be key as individuals travel back and forth. we don't turn anyone away for any reason, in particularly insurance or income. our primary focus is to provide

access to care. >> no cases of zika have been diagnosed here at the clinic. doctors are screening patient. what providers are doing is a process of elimination. it can be a heat rash, a reaction to a detergent. is it something we need to pay attention to. >> the clinic receives funding from the federal government. and there's concern that the money will not stretch to cover the response. >> we have to get ahead of the curve. the funding that everyone is receiving is enough for the population, do you have enough funding for the uptick related to zika? i doubt it. >> this clinic is great. they are watching out for us. watching out for zika and coming up next, the oscar nominated documentary about the mexican drug war.

conversation with the director of "cartel land."

the crisis along the boarder with mexico has led to vigilantes in both counties, this documentary covers both sides. i speak to the director, matthew

hinaman. >> they are taking back what is theirs from the cartel. it's what should be done up here too. >> nobody touches me, drop them. matthew, welcome to the programme. >> thanks for having me. you are not a war reporter, fight? >> i'm not. >> you have done documentaries on health care and alzhiemer's. how did you end up doing a documentary about the middle of a bloody war between the mexican drug cartels and vigilantes. >> there has been so much coverage of drug wars and media, and i really wanted to put a human face to the conflict. not talk about it from the outside, not talk about in retrospect, but put myself in the middle of the action. i embedded myself in two

vigilante groups, both fighting back agafference the mexican -- against the mexican drug cartels, and i went on a journey i never could have imagined do you think this is a failure of the u.s. and mexican government that vigilantes have to go out to fight this war. >> the failure at many different levels. i think at the heart of it is a failure of government institutions. >> lives in the days of an absent government. a government that was not there. if they were working in collusion with the cartels. living in fear of this brutal rain of the cartels, from the local judicial system and police. everyone from local tortilla makers, and beheading anyone kidnapped or got in the way.

>> many of the people in the vigilante groups are ordinary citizens, what drives them. they rose up to provide safety and security for the families and communities. they were doctors, farmers, you know, store keepers. these are not trained soldiers, this is a citizen revolution. when i started i thought it was a story of good versus evil. every day systems rising up against the evil cartel. over time i realized that the lines were so much blurred. and this was fascinating me. bit the end of the film i didn't know if i was with the good or the bad guys. >> how did you secure amazing access. >> when i approached by subjects i told them i had no agenda or

goal in mind. i wanted to follow the story, developing deep relationships with my subjects. that allowed me to get into these really, you know, sensitive and precarious situations. >> in is death-defying work. you are caught in the middle of a shoot out with your camera, right. >> several times. the first shoot out was terrifying. i had no war experience either as a journalist. i never served, and so... >> did you have second thoughts when you get in there? >> for me, all i knew was how to film. that's what i focussed on, exposing. framing, making sure the record button was on, it called me down. >> have you gotten reaction in the u.s. government on this. >> the mexican government hired a good p.r. firm, and has remained quiet, which, i think, is the best thing they could

have done. what we see in the film is the blame is dispersed. there's not one evil actor, there's many. >> these cartels killed 1,000 people 20,000 missing. you have spend a lot of time in the middle of in, there's no way out. is there a demand. with that, will come the violence, and with that the chaos, and the fear and the terror from the cartels, and also, you know, it's a failure of government institutions, and that allows the cartels to operate with impunity. we are not - besides our voracious appetite for drugs which is fuelling this, we are sending guns south, money south.

it's a vicious feedback in which many are responsible for and you can find "cartel land" on netflix. that's the broadcast. thank you for watching. ali velshi "on target" is coming up next. don't go away. i'm ali velshi "on target" tonight. avoiding another financial collapse, the real choices your elected officials will be forced to make when the next recession hits. who you vote for matters more than you think. america's economy is doing well even if turbulence in the rest of the world is causing anxious among
