Add into this people who love pits and own them, but also believe they will "turn," and so constantly give their dogs subtle cues to be on edge, stressed, and like something is wrong. They're no more prone to dangerous actions than any other breed, they're just very, very intelligent dogs that learn how to react to their surroundings. The myth of the aggressive pit is what causes the aggressive pit. We need real education on dogs in general, because that Labrador you love or the poodle who was your best friend when you were a kid is just as capable of snapping or "turning." All dogs can bite, and all breeds can be sweet and well behaved.
