I also have a problem with your unthought out comments. Yes, it is bad what happened to your father, but you would seriously take away every good pet owner's pit to retaliate for one bad dog and dog owner? THAT is selfish and ignorant. I don't think you really know anything about any breed associated as a pit nor do you understand canine traits, behavior or instinct. Even a dog raised for fighting doesn't "snap" and suddenly try to kill some random man. These aren't monsters, they're animals who have more emotion and personality than any type of dog I've encountered. You need to recollect your facts before trying to change thousands of peoples'(and their pets') lives for the sake of something that happened in your life.
BTW, my AmStaff is sleeping on his pillow behind me right now, completely oblivious that you want him murdered; yet he would still greet and accept you and may even give you a lick or two.
