That's just stupid comparing people and dogs.  There is no such thing as a breed of human.  Yes a good many pits do not attack, but the breed does have a long history of being violent.  Back in 1978 when I worked for animal control in Atlanta, GA, a pit had gotten loose, jumped a fence, ripped the throat of a beagle up, jumped the fence again, and went home.  I will never forget riding in the cage on the back of the truck with my hand over the bleeding dog's throat.  He died.  I was covered in blood.  We did locate the pit and the owner's kids had let the dog out.  We took the dog.  I'm not sure but I think we euthanized the dog at the owner's request.  It was a really friendly pit.  Also, two pits got into my yard and killed some of my pet rabbits.  They had traveled about 3 miles to my house.  They were really friendly.  I put them in the empty rabbit hutches.  I could have killed the dogs I was so angry.  The owner did pay for one of the surgeries.
