Don't know if you guys have seen this one from a few days ago. But when I saw it on national news I thought.....bet money its a Pit before I even could verify it, based on behavior alone. Defend them [bleep] all u want but IMO theres no turning back for the breed.

Cant drink a [bleep] Big Gulp in New York, but they give the owners of dogs that attack children without provocation a pass!
