I have done some research on breed banning, specifically Pit Bulls, and I must admit that while I thought there would be a definitive answer, there is not.There seems to be statistical evidence both for and against breed banning, with no clear way of knowing whether either side has fudged it's numbers or not.I'm not saying either side of this hot debate HAS altered their numbers to support their viewpoint, but it is possible.Here are a few interesting links that I came upon,which support both sides of this debate.
