Waste of time. We are talking pit bulls only.
I'm trying to tell you that any large dog breed can be aggressive and can seriously injure or even kill people. I witnessed a Chessie go for a man's throat, miss, and tear his arm open to the bone from wrist to elbow. If the man hadn't gotten his arm up in time the dog would have hit the throat and the man would be dead. As it was, it was a nasty, bloody mess (and yes, the dog was put down immediately). So far as I know, the incident was never reported anywhere.
We shouldn't be buying into the media template, because it distracts from the real problem -- careless or deliberately destructive breeders, ignorant or malevolent trainers, and irresponsible owners -- and almost guarantees that the same thing will play out again with other dog breeds, just exactly as it has in the past.
