Being raised as a fighting dog wouldn't cause a dog to attack a person. Being bred from unstable parents, being encouraged to act aggressively, or being provoked would be a more likely reason. Fighting is what Pits have been bred to do for 200 hundred years and even those fun loving, goofballs that have never seen the inside of a fighting ring have it in them, but that doesn't mean they will attack people. If the owner didn't know her dog was capable of something like this, then she didn't know her dog and if she did know, then she needs to be punished for being irresponsible. Sadly the dog will have to pay for her mistakes with it's life and the rest of us Pit Bull owners will have yet another strike against us and our dogs.
