More laws only affect law abiding citizens. Criminals don't care, besides we already have enough laws in place. Murder is against the law. Using a gun in a crime is against the law. Carrying a gun without a permit is against the law. Owning a gun after being convicted is a crime and on and on.
Blaming the inanimate object for the actions of the User is ludicrous. But then again so are the fantasies of gun grabbers.
