Most murders or gang shootings are done with illegally obtained or de-identified firearms, banning guns will just result in a whole lot of weaponry nobody is allowed to use that'll end up on the black market and in the wrong hands.
Even if you could completely ban guns, and be sure every gun in the world was destroyed, if someone wants another person dead, they'll do it, either with a knife, a blunt object, a punch, fire, etc - actually if you look at most murder mysteries, the killing is rarely actually done with a gun :P
