and darren porcher, former nypd lieutenant, and now with pace university. tony, another incident. why can't we stop this? >> purely economics. we have and have not continued the battle. we have a lot of people who are looking for a way to be able to term. at the end of the day, they'd rather take than work for it. no one is saying it's okay to get a real job and to have access to resources we're putting in your community, which they're not doing. ernie: we have tough gun laws in new york city. where are the guns coming from? >> new york city and chicago have the toughest gun legislation laws in the country. these guns are coming from a place referred to as the iron pipeline. the iron pipeline comes through places like virginia, north carolina and florida. we need federal legislation to effectively zap this problem. it's a matter of time. the problem is the nra is a strong proponent for gun legislation that protects these firearms from coming in. ernie: tony, let me ask you. the gun buyback programs, do they work? >> i don't think they really work. i think what happens is these ind

i will bring it back to daren porcher. former detective for new york police department. it's about what we feared. we were getting indications, i would say as early as the news conference an hour and a half an ago. there were several questions to the police officer on that point. there are fatalities inside the parenthood building. the lieutenant was vague, would not confirm anything at the time. it led us to believe that - we've got the press conference back. let's go back to it. >>> we mourn the loss of a very brave police officer. we just wanted to make sure that everybody knows that while this was a terrible, terrible tragedy, it could have been much worse. they were able to get-- >>> we're trying to figure it out and we apologise again. that's the mayor of colorado springs. we're having all kinds of fits and starts with our audio and we apologise for that. your thoughts now that we have one police officer killed and two civilian casualties on the scene there, inside the planned parenthood building. >>> for starters, i hear a lot of praise being extended for the firs

let's bring in daren porcher again. you're a law en fours meaforcem on this. the difference between approaching an active shooting scene and a shooter scene with possible hostages for officers. >>> the differences, we think of aan active shooter scene, law enforcement want to stop the threat as quickly and safely as possible. it involves moving in as quickly as possible. when we have a hostage situation we're more apt to take a step back and negotiate for the purr of getting the shall-- purposes of getting them out >>> you have to figure out what you have here and that might explain the length of time that it took for officers to essentially bring this situation to a conclusion. over four hours. >>> your assessment should be quick. however, the threat is what the issue was. here we had five hours, an active shooter was engaging in a gun fight with police. this person was heavily armed. it reminds me of years ago, that l.a. bank robbery, the two bank robbers >>> was that about 10 years ago? <
