it's just another routine day for sergeant mark colombo of the transit authority. by evening's rush hour, the day would become anything but routine. >> one citizen comes up to me and he tells me, i think a guy's breaking into a car over here. >> it's right downtown at boston's back bay station. and as he rounds the corner, sergeant colombo realizes he's been spotted by the alleged car thief. >> i asked him, come on. show me your registration. prove your side of the story. and that's when i reach for my radio to tell the station where i was, what i was doing -- >> the suspect smacks the radio out of colombo's hand and starts throwing punches. >> i tried to trip him up. at one point, i took him. and i had him by the back and scruff of the neck. and i actually rammed him like you would ram down a door with a battering ram into a car. and the guy went down. >> but the attacker just pops back up. >> when he got up, i was a little concerned, you know, that maybe this guy is on drugs or something. >> get on the ground now! >> on the street, people are passing slowly by as

first of all you don't need to be colombo to realize one of the daughters was the friend of a victim. an amber alert, which is ridiculous. she was 14 and they tried to convince the family she was a run away and the family told them, no she was not. >> stephanie: yeah, i guess there's some controversy, and again -- chris, i was asking you this. could they cover it up? because they would be the ones that had access -- >> it's possible. it depends on how they structure the police department there -- >> stephanie: right, because angela a lot of people in the beginning said the police are being unfairly criticized but obviously that's one of the things that is going to play out here, right? >> caller: yeah, i also think -- unfortunately we have a history in the present of police psychopathic behavior in our communities that doesn't get talked about in the main stream media, so a lot of people aren't aware of this, and a lot of people's first reaction is to automatically defend the police, and that really angers me because if you know the history and the present you wouldn't go toward that
