. >> bill bratton just came in, former new york city police commissioner.have big events, like the tree lighting. and when police in new york, expect a gathering, a large outdoor gathering of a crowd like this, they do preliminary overviews of the area to make sure they know what could happen from different areas. would that have happened in las vegas? >> las vegas, like new york, is events like this going on all the time. the event last night, the protocols in las vegas concert promoter promoters have to hire one off-duty police officer for each 1,000 people attending the concert. las vegas benefits from the fact of having a full-time s.w.a.t. unit. there's a unit all the time. the quick response in las vegas, large department, very good response to this event. >> talk about the difficulty of going into a crowded hotel, as a s.w.a.t. team, and locating the room that you believe the gunfire is coming from. that's loud. that could be one of several rooms on a floor. and carrying out the mission they did. >> i stayed at the mandalay. it's a huge hotel. the qu

. >> we're with bill bratton here, former police commissioner of new york city. you have to know shatter-proof glass, but no match for a military-style weapon to take that window out. >> i think we'll find, that's how he did it. probably shot the window out. has that platform, looking at that angle, you can see what a clear line of sight he would have had for what he did. >> bill bratton here. shawn henry here. we spoke to jake owen. he was performing at that concert, as the shooting began. we began by asking how he was doing. >> thankfully we're doing all right. unfortunately, there's a lot that aren't. it's been a pretty crazy evening here, in las vegas. we're trying to process. >> jake, you had performed earlier. you were not on the sage whetag this happened. where were you? >> i was on the stage. i had walked up on the stage with a couple friends of mine, including luke combs, who played earlier. we were 50 feet away from where jason was on stage. all of a sudden, you heard what sounded -- it was like, the thing, is that gunfire? and it got faster and faster,

i'm joined by bill bratton and shawn henry.king it's outdoors but walled in and surrounded by buildings. in this case, that's what prevented people from escaping. >> when you think of military tact tactics, you want to get high ground because you have the visibility and the opportunity to see multiple targets. in this particular case, when you're in a venue like that, the first thing you want to do is get to an egress. how do you get out of the line of fire? because the concert venue is set up, there's likely an area of tickets to come in and people are prevented from getting out of the venue. >> bill, what they try to do to prevent people from sneaking into a venue, is what traps people in that venue. >> the unfamiliar venue, the preplanning for this, you have to have a secertain number of exits to accommodate the egress of the crowd. >> because of the tens of thousands of people couldn't tell where the shots were coming direction to run. >> that's correct. >> i think about russell who was on earlier, an eyewitness. talking ab

that's what i'm thinking about. >> another one for you, bill bratton from nypd was here. he has learned there were a large number of california police officers in the crowd off-duty with their families and his belief is that a lot of these stories of heroism, people just amazed they were able to get through the crowd and to safety are going to turn out to be many of them law enforcement officers who just didn't look the part and were guests like everybody else. >> chairman of the clark county commission steve cis lee yak told me about the california police officers and off-duty officers from las vegas too, some of whom injured by shooter. they followed instincts, tried to get people to safety. one of the scariest thing, guy in 32nd floor of casino hotel shooting down into shooting ducks, almost no place for anybody to hide the way the concert was set up. people that got people out of harm's way or helped people who had been shot incredible heroism. >> this is the stuff of a war movie, don't see in urban area in western nation. as much as we mourn the dead and cheer for re

. >> we're joined by bill bratton. bratton served as the police commissioner in new york twice also in boston and the police chief in los angeles. kmegser, good to see you. you've been bringing up -- the question we've got in a lot of ways is how whether it was steve or others, how you stop that from happening again? a guy goes into a hotel with a lot of cases like our crews do. it wouldn't be an eyebrow raiser to come in with a lot of guns. >> every hotel here will have guests arriving with suitcases of weapons. there's an example of what the hotel industry has to deal with that is one of the largest conventions of its type. they will continue to seek to try to find ways to deal with this. different hotels here on the strip have different procedures and protocols. this incident is precedent setting and will result in some changes going forward but it will be done on a case by case basis. >> steve wynn's got an antiterrorism unit inside his hotel. but talk us through these bump stocks for example. why do they exist? if

fblg, bill bratton, former fndy commissioner reminded us in the last hour that some of the legislation being pushed is to legalize the use of silencers across our country. imagine the effect, the impact that would have had on the number, the list of dead and wounded in an attack like this where at least hearing the sound, being able to determine where it's coming from did help. cal perry has been looking for us at the aftermath of what was, after all, a big, joyous and live event in the world of country music. a widely promoted, widely advertised concert. cal? >> this is a very large community within the united states. this is the route 91 harvest festival. this was the fourth year that this festival had been taking place. it's a three-day, three-night festival. there are two stages that are as a part of this festival. you have anywhere between 8 and 12 acts going on at any given time. two of the stars that i want to talk about, one of them you see there, jason aldean. he is a massive star within the country music community. i spoke to a singer/songwriter friend of mine in nashville on

bill bratton, former commissioner of the nypd, nbc news senior law enforcement and counterterrorism analyst, commissioner how hard is it to prevent something like this? stanchions, blocks around various high profile areas, what more can they do? >> reality is, lester, you can't ball out the world. can't barricade every walkway. central park has thousands of people at any given time. it's actually fortunate more people weren't injured in the incident. there's a major school getting out a few minutes after this event occurred. if he had come down there a few minutes later could have been even more tragic. can't prevent them all. new york has done a very good job over the years since 9/11, but in the last 13 months, two major attacks. bombing certainly after jimmy o'neill took over from me as commissioner, and then the attack today within sight of the world trade center. >> and the commissioner noting today if not for the action of the one police officer to shoot the suspect may have been even more carnage. thank you very much. hallie jackson is at the white house. what are you hearing from th

joining me, bill bratton, msnbc senior law enforcement, counterterrorism. you for being with us. >> nice to be with you. >> the l.a. police -- the las vegas police, i should say, worked so well in this situation. but how do you prevent this kind of thing from happening? a shooter, mass murderer from a high perch against an open-air crowd of 22,000 people? >> i think sheriff lombardo during one of his press conferences said it best, who would have ever thought about something like this happening? in law enforce. private security are constantly trying to anticipate what might happen, but this one was outside that focus. it will not be outside the focus of law enforcement or private security going forward. it's a new element in the concerns that we have in this country relative to security. particularly at major events and venue, which are happening in american cities all the time every day. >> if you could stand by for a second, commissioner. i apologize, the president has just come to the podium. let's see twhae has to say and we'll come right back. >> the w

i want to bring in former nypd commissioner bill bratton and msnbc analyst. commissioner, i won't accept this is the new normal. what is this? >> this is the new normal in america unfortunately. the number of mass shootings, the pace of them has been increasing and now we have the worst ever. in policing we have talked about and now in private security over the years why we don't have more of these with the sheer availability of incredibly weaponry in this country, the number of people who are either emotionally disturbed or have grievances. it is so easy to do. this is one of many scenarios that could happen in any city at any time. the good news is social media identifies people who are putting things online. the expression in america, see something, say something. it is so important that were there signs this individual was going to do something like this, that we have notice. a lot to learn from this one. 20,000 stories. 20,000 people in that stadium in terms of personal stories, but this one is just horrific in its scale and scope and we're all dealing w

bill bratton, i don't know how much of that conversation you heard. this line here on the one hand. the nypd is gas as they've ever been in, they're as good as they've ever been as stopping attacks. this is a needle in hay stack. how do we plan in the future for security for things like this? [ silence ] >> all right. we are having an audio issue there with commissioner bratton. we'll try to fix that. it is rolling breaking news. we'll get you back in there. so that to me is the hard part to fathom here. that we have on the one hand, the terrorist incidents are smaller than ever because there's only so much they can do. >> law enforcement is amazing. >> we're really good at this. we're so much better than we've been since 2001. if you can't eliminate the risk, it is easy to say, the news media needs to temper it. when do you know to temper it? >> it is a fine line to walk. you don't want to answer their mail. you don't want to put propaganda pup helps these groups and lets them remain relevant. we may look like we're losing there but we're still relevant. look at the streets of pari

but you talk to any law enforcement officer, you talk to bill bratton, you talk to people that we praise every day for keeping us safe, they all say there's no reason americans should have military style weapons in their possession. no reason whatsoever. and after newtown i had several pretty tough debates with some very good friends and at the end of the day there's only one reason for somebody to have these weapons in their hands. only one reason. and it's only one. they will not say it. in a radio today or a tv debate. it's because they think the government is coming to get them and they want to have a stockpile of weapons and so it's to kill american soldiers or members of the american government. there are some people that just like collecting and shooting. fine. you can do what other countries do, register them and put them, you know, in the gun clubs where they stay there. >> right. >> but why do we have a group of laws that a guy can have 20 weapons, 25 weapons like this and literally kill just -- go hunting for human beings like he did a couple of nights ago. >> we're the only c
