If you ban Pit-Bulls, or Bull breeds, the assholes who use these dogs for fighting and gang activity will just start using Rottweilers, who are twice the size of a pitbull, more territorial and more likely to attack a human. If you ban Rottweilers then these same people will start using German Sheppards, Akitas, Chows or whatever else they can find. The dogs are not the problem, the people are, they are the ones who should be banned and put to sleep!
Do you even know what a Pit-Bull looks like? Take the test.
