Just how does this limp dick faggot intend to do that?
The Australian way, ban them, have a turn in period and then heavily prosecute anyone found with them after that.
Lots of ways to accomplish that over time.
Offer wives thinking of divorce a bounty to let cops seize hubby's guns while he's at work, then arrest him as he arrives home. Offer kids a bounty to turn in their parents next time they're mad at them(or a get out of jail option the next time they're arrested for drugs or driving drunk) . If there's ever a fire at your place, and somebody finds a gun in the burnt house afterwards, you are arrested.
