Aside from the 48 hours show I think PB is spot on... here in west philly you have a 13 year old kid get shot by unidentified black 17-21 year old male over a stolen bike but its right near an undercover detective who chase the shooters into a house and the homeowner didnt see anything.... unless shooters in the large urban areas are caught on video they tend to get away with shootings and murders due to neighbors or witnesses intimidated, scared or dont trust the police to protect them now a days. And in the niccodemo trial you have a neighborhood postman freely talking to police who did the shooting along with 2 others, so like PB said times have changed. The mob rat operating out in the open where he came from is classic
