You are asking for numbers and I'm providing them. The number and severity of pit bull attacks speak for themselves.
You are the one saying pit bulls aren't dangerous and I have provided mountains of evidence that they are. The ball is in your court now to provide credible evidence of what you say.
Asking for scientific studies to prove the obvious is an old Internet debate trick and I'm not biting. I've made my case with facts, now, refute it with something other than opinion, innuendo and abuse.
I am not asking for "numbers." What I am asking for, over and over, is to prove that pits are human-aggressive by nature.
I have not at any point denied that some pits have attacked/killed people. What I am saying is that this is not a natural behavior for them. Any dog can be trained to attack, and there is no denying that a pit will do more damage than, say, a chihuahua.
Again, I'm not asking for numbers, I'm talking about predisposition. Instead of looking into that issue, you are calling it a "trick" in order to avoid it, or so it seems.
You could probably Google any breed of dog and find biting/attack stores, btw.
