I have met many a pit bull at the dog park that are sweet as pie. Would I ever own one? Probably not. Dogs are bred for specific purposes and pit bulls were bred for fighting in the dog pit. (Hence the name) If you have owned a dog bred for a specific purpose (herding, pointing, retrieving, going to ground) and observe them doing the job they were bred for they are “in the zone”. I have a Jack Russell mutt and if she gets a scent in a hole she is all over it, head in, butt up and tail going a mile a minute. It is hard to snap her out of it. I imagine a pit bull on the attack is the same thing. I don’t think pit bulls should be banned or anything like that but the owners must be held responsible for dogs under their care.
Easily said, but not easily done. Quite a few years ago a woman my wife worked with was going home to her apartment when she was attacked by two pit bulls that were left un restrained in the back of a pickup by some guy visiting another woman at the complex. She had over 400 stitches initially and years of reconstructive surgery after. The police never were able to identify who the guy was (I also suspect they didn't try all that hard). The woman he was screwing either didn't know how to find him or decided not to give him up.
I'm speculating at this point, but I suspect that even it they did find him he wouldn't have two dimes to rub together, and would be unable to compensate the woman for the injury his dogs did. This is often the case with the trailer trash people who own pit bulls. They don't have the assets to compensate anyone for even a tithe of the damage their animals do.
