That is precisely the Point. Law-abiding citizens do not need weapons to protect themselves as much as the lawless ones do,An honest and forthright person will have developed an inner conviction and courage to intuitively/instinctively take care of him most of the times. So a general ban on private persons owning guns will 'disarm' the bad guys for sure. That is a good enough 'beginning' in arresting unjust loss of lives - I suppose.
