I'm hoping you meant "breed".
We all know that pit bulls are "dogs of peace" just like Islam is the "religion of peace"
All seriousness aside...this stuff seems to be happening every day now. The evidence is piling up (along with the corpses and wounds).
I know their owners are responsible for them turning bad, but how do you keep these animals out of irresponsible hands?
The same could be said of pythons kept as pets.
It's like Mason said to Dixon..."You've gotta' draw the line somewhere".
These dogs should be outlawed. Kill 'em ALL! In this case, send the stupid irresponsible sister to jail and give her house to the old lady who got mauled. Better still, put her in a cage with somebody else's pit bulls and see how friendly they are.
The dog defenders remind me of the always ever-present mamas of heartless killers who immediately jump in with "But he was such a good kind boy..."
