Investigation of Baltimore Police. The Police Union Says its the mayor that the feds should be investigating. Will Baltimore Police be forced to make courtordered changes . And north Korea Nuclear threat. Learning disturbing new details of a dramatic weapons buildup under kim jong un. Cnn reporting exclusively from inside north korea. Im wolf blitzer. Youre in the situation room. Were following the breaking flus. The pentagon raising the security level of all u. S. Military bases to the highest level of four years, level bravo, in response to isis activity. The move follows the terror attack by two gunmen in texas this week and comes amid growing kearns about isis supporters hiding out here in the United States. Were covering all angles of the breaking news with our guests inincluding congressmandown garamendi, a mech of the Armed Services committee and as well as correspondents in key locations. Our pentagon correspondent Barbara Starr begins our coverage. Disturbing information. What are you picking up . Reporter tonight already some public i vents cancelled at write Patterson Air force base in dayton ohio, because of these security concerns. With growing concern about violent homegrown extreme i689s tied to isis the u. S. Military raised Security Protection levels at all bases in the continental u. S. Law enforcement warning icie may have hundreds of followers in the country. Weve seen social media used as a recruitment tool. Reporter the immediate aware more isisinspired attacks in the u. S. Like the one in garland, texas, at a Prophet Muhammad cartoon contest. Pentagon facials say threats, though unconfirmed, against the military. The Islamic State has come out and said uniformed military personnel are a target. Reporter the new security level force Protection Bravo indicates an increased and predictable threat of terrorism. It could mean more armed troops and more vehicle and personnel checks at military bases. The new security measures will be random and for good reason. We will produce a discernible element of unpredictability in our Security Posture and procedures the new order says. Concerns grew after isis members tweeted the addresses of some 100 u. S. Military personnel, and then just last week a britishborn isis hacker published the name and home address of a top u. S. General. It was the very same jihadist believed to have urged Elton Simpson to launch an attack on that cartoon exhibit in texas. Not only do you have to secure the access to those bases, you have to ramp up security on the post itself. So this is going to be a big operation. Reporter now the big worry here is what if they get a let that is both specific and credible . Thats what the big military concern is. Right now they dont have that but what they do have as one official said to me is a rise in the temperature. Too much chatter, too much on the internet. Too much concern out there. The military is not happy about all of this uncertainty. That has led them to do this. Wolf . Barbara starr reporting for us. Thank you. Bring in our chief National Security correspondent jim sciutto also would go the story for us and learning new information. How often to these alerts go into place, jim . Reporter not often, wolf. A handful of times. Look here. Force Protection Bravo in the middle of the scale, yellow increased and predictable threat. That is key. Alpha and charlie, and look at the timeline here for when weve seen these threats on u. S. Bases in the past. One february 2003. To be clear at that time not just u. S. Military bases under threat. There was a broader department of Homeland Security threat because generalized tied to al qaeda. In the holidays december 2003 bases but also general areas around the country that were under threat. Not specific to u. S. Military bases. We saw force Protection Bravo come up again just after the Benjamin Netanyahu raid inbnin laden raid in2011. Remember the colorcoded scale and rail travel not specific just to bases. Finally again the last time we saw force Protection Bravo at u. S. Military bases on the tenth anniversary of 9 11. Again, a situation when there was a more generalized threat general raising of the Terror Threat level, not specific. Unique about this its specific to military bases. No specific credible threat but the force protection raising of the threat level is specific to u. S. Military installations. How difficult jim, is it for authorities to keep track of these isisinspired americans . There may be hundreds if not a thousand recruited through online propaganda . We know isis is very good at social media. Reporter extremely difficult for a number of reasons. U. S. Law enforcement. Hundreds of investigations for people who have made contact via social media and thousands that may have followed jihadi websites or made connections or followed twitter accounts, et cetera. Thats a big number of people and if youre going to put every one of those people under surveillance talk about in general about ten guys per person. Youre talking hundreds thousands of Law Enforcement personnel to keep them under surveillance. It become as judgment call. We saw that in the case of the text shooter. He was under monitoring but not surveillance, and this is why you have the fbi and others relooking how they make these judgments to see if they make that trigger a bit lighter, before they start to put some of these suspects under too strong a word, some of the people who have made contact, followed gigi jihadi websites put them under surveillance. Thank you. Talk about this with democratic congressman a member of the house Armed Services committee. Congressman, thanks for joining us. Do you know if this increased alert at these u. S. Military bases in california all oevlg are theoevlg over the country for that matter. The new alert issued as a result of the terror attack outside dallas this part weekend . Two Major Air Force bases in nigh district and they did indeed ramp up their protection and their carefulness. Yes, certainly the situation in dallas texas, but then also the increased traffic over the social media, particularly beginning with twitter, which obviously isil will monitor that as well as the fbi and thenen from there they move in more closely, probably getting a court order to monitor these folks directly. But im very pleased that the miller that done what it does. Take care be cautious, protect your brace whankts. What does it mean for the two bases in your district specifically on a daytoday basis . Its going to be harder to get on the base. 100 i. D. Checks. Random checking of cars. Not every car. Randomly eck whiching cars and quite possibly more secure and sensitive places on the bases ramped up security around them and probably people not being able to get even close to some of those very specific places that are on the base. One base is the big air mobility base at travis. The other is Intelligence Surveillance reconnaissance at biehl. Yeahof yeah at beal. The military sonis on top of it protecting their base and people. And a serious guy, comey, the attack in garland highlights that about the United States. Im quoting him. He said i know there are other Elton Simpsons one of the gunmen out there, its almost as if there is a devil sitting on their shoulder saying kill kill kill kill all day long recruiting and tank inging tanking at the same time and comey says there might be thousands of isis supporters followers sympathizers, already in the United States. Theres no way the u. S. Can monitor all of these people. Is there . Actually there is a good way to get a handle on it that is for the Police Agencies the fbi, local agencies to work very very closely with those communities from which these wouldbe terrorists are coming from. We have a fairly good idea where they might be coming from work closely with those communities. A couple examples in california over the last several years where the Muslim Community actually reported an fbi agent who was trying to find out he was pretending to be radicalized, and the mosque threw him out and reported to the fbi. So work closely with the communities and also the fbi and others have ways of as i said, monitoring the twitter accounts. Before they go private. And then getting appropriate court orders to monitor the private communications on twitter or item social media. Thats how they get started on this and frankly seems thats how the isil begins its work. They watch the twitter. Theyre familiar. Anybody in the world can pick up a public twitter account, and then they begin working with that individual trying to radicalize that individual. So weve got countermeasures we need to pay attention. Are you getting cooperation from the muslims in your community that you clearly are seeking . I believe so. The communities in california and throughout this state are very much american. They have a muslim faith. And they are as Good American as anybody else is and their concerned about the community. They love this country as much as anybody else does, and so they are very they have been very cooperative and i suspect will continue to be so. But the police and agencies need to reach out, work closely with those communities. Now, keep in mind that the Timothy Mcveigh was not a muslim at all. So we have other kinds of terrorists activities in the United States beyond anybody connected with isis and remember there could be a problem on the base already. Not somebody trying to sneak on the base but maybe a military personnel, soldier, airman already on the base who is recruited and becomes a sympathizer. Those individuals, like major hasan as fort hood could be a huge problem. Right . Certainly has been. And could be in the future but thats one of the things that the military has taken, i think a much higher degree of attention to, paying attention to those signs. That someone may have some psychological problem, or may be radicalized in one way or another and as i say, it doesnt have to be radical gee haudjihadism and part of the american fabric. We all need to be aware and its our responsibility as individuals to reach out when we see something that isnt the way it should be. Reach out to the appropriate authorities, and report it, and i know that that is taking place on the military bases. Its part of the new way of dealing with what happened at fort hood that great tragedy there. More questions for you, congressman, if you can stick around . Sure. Quick break.

Back with the congressman. A powerful online recruiting message out there, different, their strategy than al qaeda. Lk lk al qaeda wanted to organize plots like 9 11 get people involved. Isis wants to inspire people to go out and kill americans. Why is this isis strategy and recruitment worked so well . I think its appealing to certain part of the population in this country and around the world that is disaffective and to see something exciting. Most young people look for something exciting and i guess a war in the middle east to do some sort of violence in your own community, they would find to be exciting. Frankly, it makes no sense to me. Isis in the syria and iraq is a very dangerous and inhumane bunch of folks that are carrying out terrorism on their own people and their own community. Weve seen the beheading, but thats just part of the picture of isis but there are people that somehow find this to be attractive and want to listen and participate in it. They ought to be taking a look at whats positive in our own nation. Sure, we have troubles here, but this is you know all the positive opportunities that exist in america compared to the kind of terrorism that these folks are launching on their own community in the middle east is is not just doesnt make sense to me but apparently there are some folks, one or two of them that did this attack in texas. Were probably going to see more but we need to be aware. We need to counter with our own hope and opportunity in our own country, and we also need to take to isis the battle in the middle east. To go out, launch strikes against them when the u. S. Is doing by air both in syria and iraq. The fbi director james comey says that tracking these terror suspects here in the United States he says its like looking for a needle in a haystack but in his words, increasesingly the needles are invisible. How difficult is it to identify and stop these socalled lone wolf terrorists inspired, if you will, by isis . Well i think theres a couple of methods that you could go after. If youre going to look for a needle in a haystack, get a magnet. Thats probably the best way to find it. In this case, how do they become radicalized . Probably starting with twitter or some other social media. Probably on the public sites. Some sort of communication. We can monitor that. Its not an nsa issue. We can monitor those kind of public interactions, and then from there hone in on those people that seem to be more engaged in that kind of social interaction. And from there, reach out into the the Police Operations around the country. Notifying the police that this is something they should be aware of in the local communities as well as the local and regional fbi. Then as i said earlier, youve got to work with the communities that seem to be the most affected by this propaganda. Probably the Muslim Community more than others, but not only that community, because there are clearly others that are not muslim that somehow find this to be attractive. So work with those communities. Those communities are good lawabiding americans as much as anybody else and they dont want harm to their community, and they certainly dont want to be dragged down by someone that is in their Community Acting out a in a terrorist way. We can do a lot to identify and i think we are, and the fbi and local agencies are, and each and every one of are us also has a responsibility to keep our eyes open to watch and to be good citizens ourselves. Today marks the tenth month, start of the tenth month of u. S. Military engagement against isis in iraq and syria. Some calling it a war, and theres no congressional authorization for the use of military force against these isis terrorists. Youre leading for calls for congressional action. Do you expect formal authorization anytime soon . Im forever hopeful. But in recent days i think i have to be realistic. The house of representatives, the leadership of the house and various committees do not seem to be interested in moving a specific authorization. On the other hand, the senate has more activity and seems to be more willing to move a more precise right now the u. S. Government is operating under the authorization to use military force that rimp originated with 9 11 specifically for afghanistan and related terrorist activities in that area. R its now applied in syria and iraq and theyre also using the 2003 iraqi aumf to justify the current activity. I think neither are appropriate. I think we ought to do away with the 2001 afghanistan authorization to use force and be very very very specific.
