pittbull. jermaine jackson was apparently a bystander at the dog fight. but being a spectator at the dog fight is also a crime. when police searched jackson's home they found a pittbull mom and her three puppies and also a bulletproof vest and ammunition. inspector silver recognized 19-year-old jaquan rice. it happened at this bus stop in the bay view. it was sad irony that rice himself was the victim of an almost fatal mauling by two pittbulls when he was only 11 years old. police also found other videos of pittbulls in perkins' cell phone. this one showed two of them apparently being trained to fight by attacking hanging tires. silver suspects that pittbull street fighting goes on more than we know. >> it is not an uncommon practice at all. it is a vastly under reported practice i believe. >> silver told us street gangs use dog fighting as a means of controlling their turf.
