I guarantee you that my dog could do some damage... Great Dane. As is, I can walk her on a piece of yarn and she stays right with me, doesn't pull, tug or ignore my vibe or my commands.
Dogs have different temperaments, and it takes a responsible owner to guide them. They are pack animals, and their alpha dog...their human master... is who makes them into what they are.
Statistics are fine, but they don't tell the real situation a dog finds itself in, from owner to environment to proper exercise. Even small dogs can be triggered, and when the little ones snarl and growl, many owners smile and call them cute, not realizing that even the little ones can do some damage. Don't fault a pit for being muscular and powerful.
Some people shouldn't have animals, and most shouldn't have powerful dogs.
