If pitt bulls were outlawed what would that mean? Would all pitt bulls be euthenized? That seems like an extremely violent and inhumane solution to the problem. The suggestion of requiring all pitt bull owners to obtain a special, expensive license also seems detrimental to me as it would discourage good people from taking in rescue dogs.
The problem is human created as pitt bulls were bred to be aggressive. I beleive it is the breeders, not the dogs, that are guilty and should be penalized.
To me the most reasonable solution is to require all pitt bulls to be spade or nuetered...this will make them less aggressive and the dog can live out it's normal life and if not allowed to reproduce the breed will naturally die out.
Also...rather than coming to some arbitrary, rash, descision...there should be a committee formed of people of diverse perspectives to address the problem and find a humane solution.
