I think its a crock, pittbulls got there reputation through preforming as they wer ebred to, temperment and physical ability are both things that can be bred fo, yet as soon as someone does everyone denies that it hapens. I don't trust any predator thats big enought that man isn't incharge, its never the owners who suffer really,m its always some poor kid who loses his face or some girl who loses an arm to infection from a puncture wound, if any pieve of machinery were to start itself up and kill or injure someone so regulary as large mean breeds of dogs do it would be recalled and scrapped, but denying breeding rights to animals is ever so wrong.
