I think regulations could be put into place. Obviously, breeding should be restricted, i.e. spaying and neutering for all animals that aren't bred by licensed, educated breeders. I also think that it's ridiculous to ban a breed entirely. Guns aren't banned, and, they kill far more people than dogs do. It's more bad breeding, I think, even, than bad ownership. But, stupid people raising their dogs to be vicious, are definitely only making the situation worse for everyone involved. Outlawing a breed is only going to make it so that outlaws own the breed.
