This is the wrong thing to do.  It is not the specific breed that is the problem. The problem is the bad owners. You wouldn't ban a car maker because people get into accidents with that brand of car, because its not the makers fault, its the drivers fault.  So, why would you ban the specific breed of dog, when its not the dogs fault its the handlers fault.  First it was a fight to ban Rottweillers, then it was german shepards, now its pit bulls, when is it time to address the real issue BAD OWNERS!
