Published, peer-reviewed studies in authoritative journals of psychology and forensic science establish that pit bull owners as a whole – statistically – are more likely to be socially deviant, engage in crimes involving children, domestic violence, alcohol abuse, and violent crimes against other persons.

oh yeah another comment said something similar

A certain aggressive portion of people DO think that pitbulls are violent dogs, so they take them on and train them to be aggressive dogs. Pitbulls are strong as hell, so when they do act aggressively they cause a lot of damage

I havent done that much research, is it a case of really bad owners?
