. >> joining me now is former fbi agent and msnbc terrorism analyst clint van zandt. great to have you here this morning. what do you make of this finding the suspect at low risk of harming himself or others? does this surprise you? >> no. so many agencies dropped the ball on this. i mean, the social services investigated him. the sheriff's office investigated him. there was a mental health examination and service that he had for a year. the fbi missed one small and one massive tip that should have led us to stopping this guy. all of the agencies that we should have counted on to help us, we say if you see something, say something, the public said something. and all of these agencies let us down. >> let's talk about that. because the lack of the follow-up from the fbi after someone called in the tip from a suspect, this is a man from mississippi who noticed a comment on one of his youtube videos that said, i'm going to be a professional school shooter . so federal agents interviewed the tipster but came up short. what went wrong here? >> well, they should not have com

i want to bring in contributor and former fbi agent and profiler clint van zandt. clint, let's talk about the suspected shooter. i want to play you part of wa his attorney had to say after first court appearance. listen to this and then i want to talk to you about it. >> he's sad. he's mournful. he's remorseful. he is fully aware of what is going on. and he's just a broken human being. >> but clint, police say that this is a guy who went to walmart, got a sandwich at subway, stopped at mcdonald's. does ha square with what you're hearing from the lawyer? >> there's a couple things. the lawyer just about wiped out the insanity defense. insanity defense in florida suggests you don't know the difference between right and wrong. i did crime but i didn't know i did something bad. if he's remorseful he obviously knows he's done something bad. so let's set the insanity defense aside. then we have to consider, he's one of the few school shooters whose final act is not shooting him or making the police kill him. he had an escape plan. he threw the gun down. he mixed with the

joining me now, msnbc contributor and former fbi agent clint van zandt. e start with you. how did this statement reverberate with you and your former colleagues that there was this call back to the tip line in january. it was a process that should have been followed that would have brought that to the miami field office attention of the fbi, in fact director said yesterday that did not happen. >> yeah, i think it made every current and former law enforcement agent sick to our stomach. the fbi has a call center now where every tip line call goes into a center in west virginia. in there there's a couple hundred people who handle they get about 1,500 calls a day, about three-quarters of a million calls every year. but if it's you and i sit tlg at the desk, we take a call, we listen to what the caller says and you turn around to your boss and you say, hey, this is really a hot call. we need to do something with it now. it looks like whoever took that call for unknown reasons dropped that ball and that information never got passed forward. and people are dead b

nbc news terrorism analyst clint van zandt said previous mass shootings have taught us hard lessons. >> standard protocol across the country for law enforcement is that there's an active shooter in a school, it's your job to go in and stop that person from killing. >> reporter: after the mass shooting at stoneman douglas, students are hoping they're strong enough to return. >> it's been difficult. we've all had to grow up a a lot in the past week. >> reporter: by the way, all of this is happening on the same day that the last school shooting victims will be laid to rest. david? >> thank you very much. live in parkland, florida, this morning. i want to bring back joakim castro in texas. i keep returning to the interview the president gave to fox news. let's hear about what he had to say about gun policy. >> we would have had some great teachers that were gun adept, meaning, you know, really understood weaponry and guns, and if they had concealed permits, you wouldn't have this problem today. that coach who was so brave who ran into gunfire to protect the kids, if he had his gun concea
