i want to bring in former special agent brad garrett. the stories are lining up right now from several eye witnesses. what started as some kind of a boom or a commotionwed by shots and then the shooter going methodically from classroom to classroom for several minutes, thankfully at times finding locked doors which limited the injuries. >> exactly. it reminded me immediately, george, of virginia tech. he chained the door shut so police couldn't get in and went methodically room to room and he was able obviously to get into the classrooms. locked doors or reinforced doors i'm sure saved a number of saves today. >> and we've seen so many school districts now implement so many security measures because of the prevalence of shootings like this. >> they have. the challenge, george, is look at this school physically as we have aerial views of it. you literally couldn't sort of choke this into the school and effectively have the school function day in and day out. the ability to control weapons, knives, et cetera into a school because of the fl

i'm joined tonight by abc news crime and terrorism expert brad garrett. and brad, this suspect was captured, i know that's rare, often in these mass shootings, the shooters take their own lives before authorities can get to them. >> that's true. this guy apparently wanted to be famous alive. but think james holmes, aurora, colorado, and the movie theater. he walked out the back door and surrendered. >> and brad, the suspect was a former student, that's what we believe, at this point from authorities there on the scene, a former student at the school. what does that tell us, obviously, about possible links to some of the students still attending class there? >> because the school is the issue, david, in his mind. much like adam lanza went back to sandy hook. he hadn't been there in years. it's what the school represented in his mind. >> brad garrett with us, a former fbi agent, our terrorism analyst, brad, thank you, as always. unfortunately, always tough topics when we bring you on. in the meantime, what are schools to do in this country to protect our chi

we'll bring in former fbi agent brad garrett and political analyst matthew dowd. this first question i want both of you to answer but, guys, let's get right to the core allegation of the memo that in the thick of the campaign, the justice department, the fbi used information that was in part bought and paid for by the clinton campaign to spy on someone, carter page, associated with team trump. if true isn't that a problem, brad? let's begin with you. >> of course, it's a problem if that were true, but let me explain something, you don't have the luxury of picking where your sourcing information comes from. most of the time it is biased, but the point being can you corroborate it. just because it's biased doesn't mean it's not true. i will tell you based on experience that getting wiretaps approved, you have to have layers and layers of corroboration to get both the fbi, the department of justice and the judge to sign a wiretap order. so the idea that it was just based on a dossier is just silly. >> all right, matt. >> well, to me this thing -- i mean, obviously we

brad parscale. i think it's interesting -- >> there could be. that's part of the mueller investigation. garrettired pieces which are amazing, there is a part -- you explain the part about cambridge analytica. >> quick, we have to go. >> rumor this was coming the week after trump's campaign manager was charged with conspiracy against the united states. so, trump's looking for someone that he has -- knows will be loyal and knows his best interest at heart and brad parscale is someone who is actually allow today tweet on trump's behalf. that is all you need to know about how trusted he is by donald trump. >> thank you, garrett. thank you, nicolas. i appreciate it. >> so much fun to be here. >> we'll be right back. but i'm not standing still... and with godaddy, i've made my ideas real. ♪ ♪ i made my own way, now it's time to make yours. ♪ ♪ everything is working, working, just like it should ♪ >>> testimony today from admiral mike rogers, the head of the nsa in response to a question from democratic senator jack reid, the admiral says, president trump has not given him the authority to fight russi

brad is someone who is actually allowed to tweet on trump's behalf. i mean that's sort of all you need to know about how trusted he was. >> thank you, garrett, nicolas.here. >> we'll be right back. ♪ i thought i was managing my moderate to severe crohn's disease. then i realized something was missing... me. my symptoms were keeping me from being there. so, i talked to my doctor and learned humira is for people who still have symptoms of crohn's disease after trying other medications. and the majority of people on humira saw significant symptom relief and many achieved remission in as little as 4 weeks. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers, including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where certain fungal infections are common, and if you've had tb, hepatitis b, are prone to infections, or have flu-like symptoms or sores. don't start humira if you have an infection. be there for you, and

garrett: they beat analyst estimates on revenue and profit, which is a law still, but it was the language like him out of the statement and a call as well with the ceo bradrson to go over in november to try to patch up some of the major problems they had had over the last year. the labor to use is words like stability and confidence. he said a lot of the problems they have had over the last year have been taken care of. he said he will increase marketing spending, which is something that they cut last year and the two goats falling off a cliff as they were trying to get there should back in order -- their ship back in order. the stock jumped in the beginning part of the day but by the end of the day, it was back to where it was before the close before the earnings came out so analysts after digesting it said maybe things are not as rosy as we initially thought in the morning. emily: what remains the biggest risk factor for this company? gerrit: the biggest risk here is that competition from amazon sort of overtakes them. analysts asked brad dickerson a question, how do you come out of the gate and face some of the heavy competition from amazon and other
