“I heard the one on the Manhattan train bit someone that hit its owner. Bad idea.”
I assume you also saw the national news reports regarding this man who, when the police found him, (as usual, he had taken his dog and left the scene, running from any consequences) was then arrested for threatening to kill his (female) neighbor with the same pit bull. That, too, was national news.
Yeah, stupid owners, again. Google Rottweiler mailings or Great Dane mailings. Me and my pit went duck hunting.
