All the stats I have ever read shows that when ever you implement gun control crime goes up.Because the odds are the bag guys know the good guys may not be armed.Even with hand gun control in DC the bad guys were killing each other regardless.The only thing that the law did was keep guns from the good guys.Now if these gangster drug dealers want to kill each other let them.By the way a large percentage of gun deaths are caused by gangster drug dealers.A small percentage between lovers.A smaller percentage accidental.And even a smaller percentage do to good people protecting them selves.
