Well I don't know If they all had families, I do feel sorry for the kids if they had any. It sounds too "fishy", they were all Sgt's gunnin for this guy and he pops all four of them before they realized what happened. Cops are trained for this type of situation and it's their fault that they are dead. I don't hate cops, keep in mind my three cousins are cops and I worked Custody with a local Department for a few years, I know the biz.
cop walks up to the window and says "i need to see your license and registration". he gets shot in the face. what did he do wrong? since you know the business and all.
it was an ordinary traffic stop.
