Your statement reads that pitbulls are dangerous animals and owners need to take caution so "accidents" don't happen. So you pretty much contradicted your own statement of "Pit Bulls etc are NOT inherently bad dogs". Look at the numbers, they don't lie.
No sir you just didn't read carefully. I've kept a pit bull for a friend and she was one of the sweetest dogs I've ever met. She got along well with my three other dogs and my children. So I'm speaking from first hand experience in actually having one for enough time to know what their triggers are.
I know what can and will trigger my Llewellin Setter and I make sure that he is not exposed to those triggers. I know what can and will trigger my Boxer Jack Russel mix and I make sure that she is not exposed to THOSE triggers. If I currently was in possession of a Pit Bull I'd ensure that it was not exposed to triggers that could set it off and / or make damn sure that it couldn't roam freely just like I would any other dog, cat, squirrel, or any other pet I could possibly own.
Let me give you an example.
My neighbor had a brown lab. One of the sweetest and loving dogs you could ever know. She had never shown an aggressive tendency in her life. One fine day he had her in my front yard while we were talking about life it's own self. My mini schnauzer (God rest her soul) came walking up and, for reasons we never figured out, his lab ATTACKED my dog. When we got them apart he was mortified and apologetic. Fortunately my dogs injuries were minor. What did the owner do? Paid for my dogs vet bill and we ensured that they never mixed again. Apparently his dog just did not LIKE my dog. But there's more. He added security to his back yard to make sure that she couldn't get out and never let her near a small dog again. That's being responsible.
