Terry Caldwell wasn't really connected to any kind of street gang though; he'd been a close friend and associate of a few Bonanno wiseguys for years.
The shooter who was caught on camera during that botched hit on Salvatore Zottola struck me like any modern day street gang member. I wouldn't put my money on this being an ordered mob hit. Though of course you never know, the times are changing and cooperation between different organized criminal outfits - be they mafia, other ethnic mob outfits, street gangs or biker groups - is more common than ever.
