[captioning performed by the national captioning institute, which is responsible for its caption content and accuracy. Visit ncicap. Org] scott hello, im scott thuman in for Sharyl Attkisson. The term sanctuary city has generated a lot of headlines and a lot of controversy. Throughout his campaign, candidate trump spoke out against them, and less than a week after he was sworn in, signed an executive order to cut off federal funds to sanctuary cities. Many local leaders responded by doubling down on their promise to protect undocumented residents. But one county in florida went the other way, immediately changing its policies. This weeks cover story is sanctuary shutdown. Shame on you shame on you scott in south florida, temperatures were hotter inside than out, after the miamidade commissioners signed off on the mayors plan for the county to become less of a sanctuary. President trump we are going to get the bad ones out, the criminals and the drug dealers and gangs and gang members and cartel leaders. Scott 24 hours after President Trump announced a plan to cut cities, mayor Carlos Gimenez became the first local leader to fall in line. Mayor gimenez we are an inclusive county, we are a county of immigrants, i am an immigrant to this great country. We are also a country of laws. Scott miami has one of the largest immigrant communities in the country. More than half its residents were born overseas. But an estimated 160,000 immigrants are in the county illegally, and how to handle the ones who have run afoul of the law has divided the community. Cheryl little and i can tell you, i was shocked, when someone called me and said, did you just hear what mayor gimenez did . I didnt believe it. Scott cheryl little runs americans for immigrant justice, a miamibased notforprofit that provides legal aid for immigrants, those who are here legally and those who arent. Cheryl i mean, this is an immigrant community and theres a real sense of betrayal here, and i dont know how long its going to take us to get over it. Scott the mayors new policy requires local Law Enforcement to keep anyone already arrested and jailed for an extra 48 hours if federal immigration authorities want to pick them up. For Illegal Immigrants, an arrest for drunken driving, robbery, or even Disorderly Conduct could get them on a fasttrack to deportation. Cheryl what were probably going to be looking at moving forward is that long term residents, people that have lived here for years, worked hard, paid taxes, have u. S. Citizen children are going to be filling our immigration detention centers. Families are going to be torn apart. Monica so basically, if my father gets stopped or any undocumented immigrant gets stopped at the moment, that could end them up in their country, just being deported. Scott monica is a client of littles. Sh honduras at the age of nine. A socalled dreamer, monica is protected under an executive order signed by president obama. But she worries about her father who has been living in the shadows for years. Monica a single dui checkpoint which, my father, you know, my father does not have to be drunk or anything or under the influence, but just the fact that hes being stopped because its a checkpoint, he could end up in jail and then getting deported. Scott thats a point mayor gimenez strongly disputes. He says in Miamidade County, any nonarrestable crime, like a Traffic Violation or driving without a license, will result in a citation, not an arrest. Mayor gimenez those folks with minor crimes wont be arrested. And remember, we dont know if you are undocumented or illegal when you have an interaction with miamidade police. We dont ask the question, its frankly none of our concern. If, however, you commit a crime that anybody else would be arrested for, thats what youre go scott according to data we obtain from Miamidade County, 60 individuals have been held since the policy changed. They have been arrested for serious crimes like first degree murder, aggravated assault, and burglary, but a handful of cases included lesser crimes like Marijuana Possession and aggressive panhandling. Gimenez insists the policy is narrowly tailored and focuses on serious criminals. But at a meeting with the Nations Police chiefs, President Trump made it clear he wants Law Enforcement to cooperate with federal immigration officers. President trump you know the bad ones, you know the good ones. I want you to turn in the bad ones. Scott President Trump isnt just demanding that Law Enforcement hand over immigrants after theyve been arrested. He also reinstated secure communities, a program started in 2008 by president george w. Bush that encouraged information sharing between local Law Enforcement and federal authorities. Many Illegal Immigrants makes a mockery of all those who are going through the process of immigrating legally. Scott president obama inherited secure communities and ran with it. The Obama Administration deported 2. 4 million people, earning him the nickname by critics as deporter in chief. But in 2014, the Obama Administration modified the program, opting for a more discriminating approach that prioritized the removal of violent criminals. Scott if this system were refined to the point that only the most dangerous convicted undocumented immigrants were deported, would there be anything wrong with that . Cheryl look, i want our community to be safe. I mean, every immigrant i know wants our community to be safe. What i dont understand is why we have to be spending taxpayer money rounding up people whove committed no crimes or who have been charged with petty offenses. Scott as his executive order makes clear, President Trump is widening the net of who qualifies for deportation and also bringing back a Controversial Program called 287g, that deputized local Police Officers to ask residents about their immigration status. Mayor gimenez is adamant that he is only complying with one portion of trumps executive order. Mayor gimenez we will not be immigration officers, i dont know how much clearer i can make this, okay, that Miamidade CountyPolice Officers will not be immigration officers. Period. Scott when you hear people on the other side of the argument say, look, it is a burden on our system, what do you say . Monica we are not a burden. The government gives me zero aid, i go to school, i pay everything out of pocket, i do not get any loans, any financial aid, i do not qualify for food stamps, i do not qualify for any relief on insurance. Where is my help . How am i a burden to anyone in this country . If anything, im helping the economy. Scott in the weeks ahead, well visit a sanctuary city vowing to stand up against the executive order and federal authorities to shelter Illegal Immigrants. Ahead on full measure, a look inside the deepest, darkest parts of the internet. Scott the latest wikileaks revelations, purportedly revealing cia hacking tools and techniques, are a reminder of is. A big area of concern the socalled dark web, a largely hidden online world where some of the most serious crimes are committed. The fbi has dedicated teams to battle cybercriminals and one of their agents agreed to give sharyl an introduction to the dark web. Chris christopherson we work the National Security side and we work the criminal side. Sharyl fbi special agent Chris Christopherson agreed to show us how the dark web works, inside the fbis first Regional Computer Forensics Laboratory in san diego. S. A. Christopherson so if you think about this iceberg here as content up on the internet, the dark web or the deep web represents everything thats underneath that water level and then what we see on top of the water level is represented by content that google sees. So, things that you can access through regular Search Engines and then things that are underwater or on the deep web. So what were looking at here is a website where you can actually go ahead grab some software, this tor browser, that would enable you to go on the dark web or the deep web. The idea of tor is two parties, they dont know the other party in the communication. Theyre just communicating. So google actually doesnt know where to go, because everything is so anonymous, and the encryption, its obfuscated, google just simply cant find it. Sharyl like the silk road website. S. A. Christopherson exactly. So google, if they could would index it, but at the end of the day if you dont know where it is, you cant find it and you cant search it. Sharyl silk road was an online black market launched on the dark web in 2011, primarily to sell illegal drugs. S. A. Christopherson we put up a site and banner to notify the people on the forum, on the marketplace, say hey, were investigating these things. It is illegal, and these are crimes, and youll get punished for them. Once we identify you. Sharyl if someone visiting that site went to it and saw this, im sure theyd be a little concer activity. S. A. Christopherson thats what were hoping for. Yeah exactly, yeah. Sharyl the fbi shut down silk road in 2013. Its operator, ross ulbricht, was convicted of money laundering, computer hacking, and drug trafficking. S. A. Christopherson the guy that ran silk road is sentenced to a long prison sentence and so on. Weve seen how the investigation has actually broke though some of those anonymity borders. Where at the end of the day, drugs have to get sold and delivered. So even though this is online and anonymous, there still has to be some component thats real world and not anonymized. And thats where the fbi and other Law Enforcement agencies can kind of come in and identify the actors on this forum and others. Sharyl another crime found on the dark web involves cyber attackers who infect your computer with ransomware and encrypt your files and folders. You might not know it until you try to get data and see a computer message like this. S. A. Christopherson if youre infected with this ransomware and you start to utilize your computer, open files, youll see and what you can kind of see at the top is that the ransom itself is 500 and you have a countdown timer here, so once that countdown timer hits zero, the ransom will double. So what theyre trying to do is to ensure that sort of time sensitivity, so that you go through and go through the difficult process of finding one of these exchangers, getting bitcoins, and so on. Sharyl bitcoin is a payment system, a new kind of currency, thats anonymous, with no central authority. Cybercriminals Holding Information for ransom often demand payment on the dark web in bitcoin. S. A. Christopherson theyll have their Bitcoin Wallet information on there. Theyll have information about how to pay the ransom. So this is something that they need to actually send out to all their victims anonymously. The internet with anonymous traffic is synonymous with the dark web. So the dark web iseally conducive with this kind of criminal activity. There are local bitcoins, as you see here, where i can actually meet facetoface with someone in person, give them money, and get bitcoins from them. And then there are atms, even here in san diego, where you can get bitcoins from the atm. So you can either purchase bitcoins in the atm or you can trade the bitcoins in for money. Sharyl but do the crooks then exchange it for cash and spend it or do they buy other illicit things with it . S. A. Christopherson mhmm. So thats a good question. Can i buy groceries with bitcoin . And the answer is yes, you can in certain cities and places, you can buy subway, you can buy martinis, you can buy groceries. But at the end of the day, theyre probably going to exchange it for cash. And so they can use these same exchangers to turn their bitcoin into euros, dollars, or whatever theyre looking for. Sharyl when people have their emails stolen, their email addresses, and things like that from Retail Stores like weve heard of, is this what some of them are potentially used for . S. A. Christopherson exactly. So there will be certain trading on the dark web of email address of victims. Theres also the potential that once someone pays a ransom once, their email address or some other identifier might be sold or traded on the dark web, and now theyll be targeted again. Scott to help protect against ransomware attacks, the fbi recommends backing up your data regularly and keeping the backups separate from your internetconnected computers.

Com scott north korea conducted a new round of missile tests this week. At the same time, u. S. Forces in south korea began deploying a controversial new Missile Defense system. We spoke with bruce klingner, a former cia Deputy Division chief for korea, about some support in congress for a preemptive strike. Bruce klingner we should always be very worried about north korea. As some on the peninsula have said, were always you know sort of aec four u. S. Fourstar generals think north korea already has, or we have to assume they have for planning purposes, the ability to hit the United States today with a nuclear weapon. Scott that sounds daunting. Bruce it is. Thats why you have growing discussion or perhaps advocacy for preemptive attacks. Scott at the beginning of the year, before his inauguration, President Trump tweeted about north koreas efforts to build and Deploy Nuclear longrange missile. He said, quote, it wont happen. Is the president right to make a promise like that . Bruce the problem is, we dont know what he meant. Even rex tillerson, his secretary of state, during his confirmation hearings, he was asked, does that mean mr. Trump simply doesnt think north korea can do it . And he said, well, it could mean that. And then asked mr. Tillerson, do you think hes drawing a red line that he might use military force . And he said, well, i dont think he meant that, but he could mean that, too. Scott so theres no way of knowing if thats a red line . Bruce its the problem of it leads itself to misinterpretation. Scott what have been some of the other administrations missed steps in handling north korea . And what could President Trump do differently on that front . Bruce well, i think we first have to identify that there is no administration, no Political Party has a monopoly on good or bad ideas on north korea. Experts have been trying to solve north korea for decades, so we need to realize that north korea is the problem, its not a specific u. S. Administration. Scott president bushs administration removed north korea from the list of state sponsors of terrorism. Bruce correct. Scott that was in an effort to get them to play along a little bit. Is it time they go back on that list . Bruce i think it is. Theres actually been a really long list of actions by north korea since they were removed from the list in 2008, which i believe, qualifies them for that. Theres been shipments of conventional arms to terrorist groups, hezbollah and hamas. There have been attempted assassinations or successful assassinations of north korean defectors in south korea and russia and china and now malaysia. Also, you know, if we think back to when north korea conducted the cyber hack on the sony studios, not only was it the hacking, it was the threats of 9 11 style attacks on any theatre and theatregoers that went to see the movie, the interview. Thats a threat of a terrorist act. Scott president obama reportedly on his way out of office had warned incoming President Trump that this was going to be one of his greatest concerns, if not one of his top priorities. Is that a Fair Assessment . Bruce i think its very fair. North korea really is a Broad Spectrum of military threat. Its got the nuclear weapons, its got the missile means to deliver them, as well as deliver conventional high explosive warheads. It also has 5,000 tons of chemical agent, we estimate. It has a biological weapons program. It has a millionman army Forward Deployed near the south korea. South koreas capital, seoul, is within artillery ra
