there was one show on AP or nat geo, i can't remember, about a lady running a giant shelter at her home and retraining 'problem' pitbulls to give to good homes. she also would visit schools explaining how it's not the dogs, it's about the owner and how taking care of an animal correctly can change everything. it was a great show.
i've always been scared to DEATH by rotts, pitts, and most dobermans after nearly being attacked by a dobie as a child. it's also probably stereotyping but i almost adopted a pitt from a shelter before i discovered layla. i think in the wrong hands, any dog can have aggression issues. a pitt bull's instinctive deathgrip sure makes me uneasy, though.

i think they really are beautiful dogs being so muscular and whatnot, however.
