is. so that is the latest here from watertown, which i can tell you visually is buttoned up tight. now i want to toss to some sound from a witness who witnessed some of what was happening last night on the streets here in watertown. take a listen to this. we thought we heard firecrackers, so me and my son looked out the third floor window and we heard gunshots. and then we saw the explosion. i actually saw a black suv come down laurel street and cross over dexter, it looked like it hit a police car and they were just shooting at that. we must have heard about 60 gunshots. reporter: that is similar to what other witnesses i talked to, it sounded like a running gun battle car to car through the streets. and at one point the police issued a notice that they had to clear the streets to make sure
