Families alerted local authorities first they were missing. I it became apparent in a few days they went to National Security officials and went to the middle east likely trying to get to syria in the hopes of joining isis. And the fact remains, anderson that these families are frantic right now trying to figure out what actually happened to their children. So their exact location right now is not known. Reporter no and in fact Security Officials on the ground in turkey are trying to help canadian officials but as we just discussed, anderson there are many westerners right now that security authorities are trying to track, and its a huge problem. And the trail has, in fact gone cold. And once they step over to syria, it is very difficult to figure out exactly whats happened. You reported the canat canada started revoking passports. That did not happen here. Reporter we covered it for years and talked about in britain, whats different in the canadian cases . These families are alerting authorities. The problem, in these cases, it didnt happen early enough and a lot of parents are speaking out in canada saying i want those passports taken away from my children. When they find out whats going on and alert the authorities, they have the legal power to revoke the passports. Fortunately, it didnt happen in this case and anderson you know tonight the quebec Public Security minister saying shes finding that radicalization is a growing problem here in canada. Paula, i appreciate the reporting. Paula newton from canada tonight. The young british man from a well off family with a College Degree has become the global voice in some cases of isis. Today, we learned from a number of sources including several highly placed intelligence officials that the isis executioner you see there with the english accent who first appeared in the murder video of american james fauxoley is a londoner. Jihadi john is actually Mohammed Emwazi emwazi. Talked about the news and what she thinks should happen to him. I think all the families will feel relief once theres a bullet between his eyes. They might just get their wish. Cnn telling Barbara Starr this man is considered a highvalued target right now. We have more on how he came to be identified from our chief National Security correspondent, jim sciutto. Reporter hes been the voice of some of isis most brutal terror videos. Calm ruthless and with a distinct and surprising british accent. Our knife will continue to strike the next of your people. Reporter now u. K. Authorities have identified terrorist known as jihadi john as Mohammed Emwazi a 26yearold British National born in coupkuwait but raised in london. Would not publicly discuss his identity but said jihadi john is a top terror target. In the mind of the president , he ranks highly on the list because that individual is responsible for the murder of americans and the president is determined to bring to justice. Reporter it was the broad appeal from a well off family earning a College Degree in technology at the university of westminster and until his travel to syria in 2012 enjoying a life of privilege. He was a diligent, had workrd working young man. Polite quiet. Everything youd want a student to be. Reporter today, his friends never saw signs of his future as a terrorist. He was such a beautiful young man. Really. You know its hard to imagine, but its not unfamiliar for us. Reporter emwazis path to radicalization may have happened when he went to tanzania a safari a present from his parents. He was deported to the u. K. Authorities suspecting his true intention to travel to somalia. In 2010 detained again by counterterrorism officials in britain. Two years ago later, emwazi is believed to have traveled to syria where he joined isis. His friends claim mistreatment by british authorities set him on a path to terrorism. Our entire National Security strategy for the last 13 years has only increased alienation only increased people feeling like they dont belong. And jim sciutto joins us. Now it seems like he was on a path already if authorities are correct. Thats why he went to tanzania. U. K. Authorities knew about this guy going back to 2009. Hindsight i guess its easy to say, but clearly, they didnt do enough. Reporter we saw this with the kouachi brothers in paris with the paris attacks. They had been on french authorities radar. A lot of these potential recruits take steps that are worrisome but not enough to be sure to indicate that theyre going to carry out jihad join a group like isis. From just a perspective, you cant track and arrest everyone. Two, from a legal perspective, oftentimes the first illegal step that these guys will do is try to hop on that plane to go to syria. We have that case with some of these brooklyn suspects just yesterday. Thats when they were arrested when they got on the plane. In this case jihadi john got on the plane in 2012 and continues on the horrible path and last summer he became the jihadi star appearing in the videos. Its got to be so frustrating for Law Enforcement and intelligence officials with connections with them who took him into custody from time to time but not enough to actually hold him. Today, the director of National Intelligence, James Clapper, he gives new information about the number of americans who actually tried to travel to syria. Reporter he did. He raised that number to 180 and keep in mind so this figure as you say, its people who have either gone to syria and iraq successfully including the group such as isis or have tried to go some of them killed there. So its a broad number. Its an estimate but the estimate has jumped. Last year that number was around 50. It creeped up to the 70s. It creeped up to 100. A short time ago, it was 150. It is growing and partly its growing because more people are attracted and also growing, anderson, because theyre making a better effort to keep track of these people but, you know, thats a worrisome sign. Its not to the level you see in european countries, several hundred in the u. K. And in france et cetera. But still, thats a significant number and thats already a difficult group of people for u. S. Authorities to follow. Yeah. Jim sciutto, appreciate the update. Thanks jim. Yeah. The killer in question grew up in a city in london that was a hot bed for radicalization before isis existed, something maajid nawaz was in and now joining us with counterterrorism official phil phillip mudd. Theyve known for a while and keep it on the down low. Now its out there, does it that make easier or harder to capture him . I dont think capture is likely. First, get the intelligence not only where he is today but where he is tomorrow and second take the risk of putting somebody i suspect over time he will be identified and killed either by u. S. Forces a syrian striker among extremist groups. I cant imagine despite what they say bringing back for justice hes going to come out of there. Maajid its interesting. Weve talked about and a lot of people focused in the past about radicalization and other things that lead to it, poverty, lack of opportunities, sense of humiliation. He wasnt poor. He went to college, had a degree in computers. It seems like theres no boundaries anymore for somebody who actually may be attracted to this stuff. Well yes, anderson. Ive written a piece for one of the National Newspapers the guardian comparing it to racism. Whether educated or not, its an excuse for their own insecurities and islamist ideology is the same. Not only graduated from westminster in london but others who controlled the Student Union, not just the Islamic Society but the Student Union in that university were affiliated with my own former organization the first group to popularize the notion of reestablishing a caliphate. The idea of recreating an Islamic State effects in a disproportionate way the highly educated born and raised in britain. What is the appeal though . You believe, what its personality traits or leading somebody to this in a case like him . Probably. Once they tried to work out whether hes british, kuwaiti or muslim both. That combined with charismatic recruiters such as al bagg da dehdadi, the socalled caliph. And western born muslims to this ideology. Filipp phillip, if another country was interested is the fact hes british, does that play in . I think theoretically, a country, can you imagine someone targeting a u. S. Citizen with a drone strike and not telling us if its a close ally . This is a pretty clear case though. If you look at somebody involved in terrorism and what we call in the business an imminent threat not only involved in murder but most likely today, i dont know how you stand back and say, look because this is a citizen of a close ally we wont take a shot. This guy is clearly over the bar. Is it likely hes actually a high level or just happens to be the guy they picked to talk on camera because hes got the accent and able to speak english . I think this story is misleading. Hes a target not because hes operational command. You would think, hes a big player. I would say, hes not my top tier target. The guys running the organization training. That said in the 15 years of this war, somebody with this magnetic appeal across the explosion of social media, you wouldnt have targeted this person 15 years ago. But because of the magnetic appeal and ability to reach out, hes got to be on the list. Maajid youre concerned about people having sympathy for this guy and almost make excuses for why he was radicalized because this group cage lays for the British Intelligence agency. Yeah. I mean look. I know the guy from cage. I went to university with him. These guy are islamist sympathizers. I have seen him spoke at a rally outside of the u. S. Embassy in london alongside me supporting groups such as ezhezbollah, hamas. They subscribe to the ideologies. Its no surprise theyve been spending the day on british media defending Mohammed Emwazi. In fact the spokesman for cage basically said Mohammed Emwazi was a beautiful young man as he knew him and then he actually shed a tear live on air when he was reminiscing over this socalled jihadi john and yet didnt shed any tears for any of the victims of this beheader. Others that this man brutally murdered. Showed no remorse for the deaths and no consideration for the family and this is typical of a halftruth narrative of playing the victim constantly and blaming Foreign Policy blaming torture. I have opposed Guantanamo Bay and on the george bush jr. Just because we oppose the invasion of iraq or guantanamo doesnt mean islam is the solution. This has to be debunked. Maajid nawaz and phillip mudd thank you. Take you inside the terror groups empire and the way to counter that message. Look at one of the latest propaganda videos destroying precious artifacts at a museum in mosul. Why is this something to brag about . The answer says something about the interpretation of islam. Fact. Fastacting advil is designed with an ultrathin coating and fast absorbing advil Ion Core Technology stopping headaches and other tough pain. Fast. Relief doesnt get any better than this. Advil. You can call me shallow. But, i have a wandering eye. I mean, come on. National gives me the control to choose any car in the aisle i want. I could choose you. Or i could choose her if i like her more. And i do. Oh, the silent treatment. Real mature. So you wanna get out of here . Go national. Go like a pro. Huh, fifteen minutes could save you fifteen percent or more on Car Insurance. Everybody knows that. Well, did you know words really can hurt you . What. . Jesse dont go jesse. No im sorry daisy, but im a loner. And a loner gotta be alone. Heee yawww geico. Fifteen minutes could save you fifteen percent or more. Jesse .

I have got to update my ink. Again, breaking news. Canadian authorities saying at least four young people from quebec province left the country last month. The cbc reporting they now reported militants in syria. Back in america, we learn how the case against three alleged isis reporters in brooklyn began. Daeb Deborah Feyerick saying it was after a post he allegedly wrote on a web site threatening to kill president obama. The threat was brought to the attention of the secret service last summer. Investigators say that all three men spent time online apparently becoming more radicalized. One official telling the New York Times theres no indication they were mote vaited by anything they heard at places of worship. That leads back to the machine that jihadi john was a part of. Without a production film more credit or publicity than Something Like that deserves we want to briefly explore how they operate. Our randi kaye investigates. Reporter you might think this is a commercial from the tourism board of canada. Its actually a video from isis posted on social media aimed at convincing why to be jihadis in syria. Islam in syria, i come from canada. Reporter andre, a canadian convert, was the ultimate pitchman for isis until he was killed fighting for them. But even that wont stop wouldbe extremists from searching out isis online. Connecting in memberonly chat rooms but is it that easy to contact isis online . When these wannabe isis say theyre emailing, are they . Its a representative. Reporter its available at all sorts of languages including english. Why arent they shut down . Some of them are hard to find. What are you going to do, shut down all of twitter or facebook . Theres one called v contacte. If youre from uzbekistan or kazakhstan you have the language you have russian. You can easily link up with networks on here. Reporter and find somebody to go do jihad with . Sure. Reporter its that simple . Yeah. Reporter in fact using this uzbekistan web site. This is one that crucifies others and sub jewujugates. Its designed to attract jihadis because they show people going after, yazidis, christians whatever. Reporter even more frightening . Hooking up on social media may mean these wannabe extremists assign them deadly tasks from afar. Stay where you are. Were radicalize you and then teach you how to build a fertilizer bomb in your facebook. Reporter a dangerous directive from a group whose popularity is only growing online. Randi kaye cnn, new york. We want to dig a little deeper now to the means and methods of radicalization. We are joined by graeme wood who recently posted what isis really wants. What attracts some people to isis you write that western recruits are, quote, ready to give up everything at home for a shot at paradise in the worst place on earth. Explain that. What is that appeal . Reporter so these people were trying to leave the United States. They may have been looking for ways to attack the United States but they really wanted to go to syria in the Islamic State buzz they think to fulfill their destiny as muslims and really live their religion they have to be in the Islamic State. We dont know exactly the motivations of these particular people but thats usually why people are going there. How do you begin to counter that kind of propaganda . How do you compete with an organization thats promising, you call it kind of a death cult and promise nothing less than paradise to the people they recruit . I think you have to acknowledge exactly what is being offered. And then show its not actually there. If they think they have a utopia that theyre going to you can show them that actually theres a place full of unequity no better at providing for citizens and allowing to live a nice pious life. I think youve got distance toward making that propaganda not so attractive. The video isis released today of militants destroying artifacts in the mosul museum in iraq im reminded of destroying the statues of boou da back in 2001. It gets to the heart of what this movement is. An attempt to get rid of all competing civilizations and cultures. When they do control a place like mosul, i am surprised it took them this long to attack the statues with hammers. So much in mosul they could go after and already destroyed mos. Theyve already destroyed shrines. They want to purify everything around them so it only follows the particular variety of islam that they follow. Michael wright in randis piece, said while they destroy on camera they sell a lot off camera. Weve been hearing for month the trade in antiquities is a source of income. Yes. They are certainly very active in sale of antiquities. Things reach the market that have come through their ends. Essentially, they have no value for these things at all. They would love to trade them for cash. They would also be happy to pulverize them and turn them into dust. The article you wrote for the atlantic really fascinating, i encourage people to read it. Isis is very islamic and i wonder what kind of a response you got to that. When you got on the program, you were talking about how many people in the muslim world say, theyre unislamic. Theyre defiling the religion of islam, but youre saying according to the isis interpretation theyre following very strict codes and teachings from way back. Yeah. Theres the distinction i would draw between being islamic and the right variety of islam. Almost all muslims say they practice the wrong islam but the traditions are the same islamic texts that are recognized as holy by all sunnis certainly, and were talking about
