. >> pete, let me put a question to you i asked jim cavanaugh earlier in the hour, given that mr.-- is with the federal protective services, how does that factor into this investigation? >> well, not much frankly other than they have to know this is a person with law enforcement experience so he would know what kind of things police would normally do in these situation, although our understanding looking at his background we have not seen any indication he ever worked for a local police department. he's had other jobs with the federal government doing similar kind of building security but he would have had law enforcement training. all of the people in positions like his get training. that's an additional thing police have to be worried about here, someone who knows how they operate and someone familiar with firearms and obviously comfortable around them and could have heavily armed himself. i don't think it's a huge factor but it's certainly something they will be looking at. >> pete, stand by for us. i want to bring clint vansant back into this discussion. you were talking about

let's bring in jim cavanaugh, the expert. me, as you said in an earlier appearance on this net work, this is going to be a rolling thing. it's going to go from now at least to the conventions. will police have to mount up, bulk up with more officers on the street, more weaponry, more whatever, horses even, and that will rile up the crowds to escalate as well? >> i don't think we're going -- i think we're going to see this all summer. i don't see an end to it require think you see the thin blue line in action here but it's reserved police action, officers dealing with civil disobedience, so far on a minor scale. water bottles thrown, a lot of the taunting, people dancing in the street. but fights break out, some arrests made. like jacob said what's going to happen now is unlawful assembly is declared and you'll see that team of tactical officers in the near future try to move that crowd, without gas, just by walking and walking and try to move the crowd to disperse the crowd. they'll kind of try to do that slowly. if there's v

jim cavanaugh, former special agent in charge of the chalcoho tobacco and firearms administration is with us. no notably, jim was around during the washington, d.c. sniper case. it has nothing to do with this case, jim, except, speaking of i c conography, these live pictures of shopping center and mall parking lots, in this part of the world, for those of us who were around then, can only bring back one memory. >> no, that's right, brian. i can't say enough about the montgomery county police department and its detectives, of course the law enforcement in the whole capitol region, prince george's county and surrounding counties and state police and maryland will be involved and federal partners as well. you have top cops here, top departments, great the detective bureau s, they're on it and trying to get the answers you and pete were just discussing. the biggest one is, is it the same guy. you posited that at the top. the biggest question is the spent cartridges at these three sce scenes. if they can match that up the answer is it's a center if it's the same weapon. if they know that,

let's hope they can be peaceful. >> law enforcement analyst, jim cavanaugh, thank you. we have heard from donald trump and shown some of the protest video. we want to go directly in and speak to the head of the san diego county democratic party, which is one of the groups coordinated these protests. let me ask you directly, for folks watching directly at home, whether they agree with your goals or not in the election, what are you trying to convey through organizing these protests today? >> first of all, let me say that everything that we've done, we have emphasized this is a peaceful protest. our goal is to raise our voices and challenge donald trump. he has a lot of divisive and hateful rhetoric. he has called out latinos and mexico. he has ridiculed leaders. he's lied about how he supports veterans. if we don't stand up and call him out and hold him accountable, then we're not doing our job. we do encourage people to make their voices heard at the ballot box and vote. i want you to know that san diego has twice as many democrats in the city as republicans. san diego

's a drone youl with your brain, which controls your thumbs, which control this joystick. no, i'm actually over at the ge booth. we're creating the operating system for industry. it's called predix. it's gonna change the way the world works. ok, i'm telling my brain to tell the drone to get you a copy of my resume. umm, maybe keep your hands on the controller. look out!! ohhhhhhhhhh... you know what, i'm just gonna email it to you. yeah that's probably safer. ok, cool. ...to cook healthy meals... yet up to 90% fall short in getting key nutrients from food alone. let's do more... ...add one a day men's 50+. complete with key nutrients we may need. plus it helps support healthy blood pressure with vitamin d and magnesium. you've finally earned enoug

perspective what's going on former law enforcement analyst former fbi special agent in charge, jim cavanaughnts ago we heard from jim miklaszewski outside the white house. he said the veteran reporters who have seen a lot going on at the white house through the years never remember seeing the decontamination understand brought in like this raising some chatter there might be something going on with this suspicious package. can you offer information why a decontamination might be brought in like this? >> sometimes when people leave bombs or packages they write something on this or write a chemical contamination or anthrax on it. sometimes the container indic e indicates that you might have to go to a hazmat operation. that's one possibility. people tossing over the white house fence are arrested pretty quickly. rarely do they get away, so many uniformed secret service and metropolitan police and d.c. police all there they will grab you pretty good and that person can say something and make a threat i have a chemical in there and biological agent in there and immediately throw the secret servi

and jim cavanaugh is with us, retired alcohol, tobacco and firearms special agent in charge, after three decades with atf. jim, it's good to have you, and i wanted to reference, some of these pictures can look so menacing to folks. i mean, i imagine a family a week away from summer vacation, their long-planned trip to washington. they're seeing pictures of a uniformed secret service agent that we keep showing on the roof of the white house, panning his sniper rifle back and forth, right there. we should point out to people, that's to use his scope, his optics. you see a tripod on the front of the weapon. it's not because he was going to spray anyone with gunfire. he was just using his scope to get a beat on the scene. >> exactly, brian. they're very disciplined there. no one should worry if they're going to washington. situation normal. the secret service, both the agents in uniformed division, are very thorough there. they tightened up, they got a new director. they were under criticism a year ago or more. it shows real courageous action here by the uniformed division officer. ordered t
