...Virtually never are murderers the ordinary, law-abiding people against whom gun bans are aimed. Almost without exception, murderers are extreme aberrants with lifelong histories of crime, substance abuse, psychopathology, mental retardation and/or irrational violence against those around them, as well as other hazardous behavior, e.g., automobile and gun accidents.
A handgun ban is not realistically enforceable.
