You have to look at the UK and Australia for the answer.

A few diehards in Australia were killed when they refused to surrender their weapons, including the actual "Crocodile Dundee" fellow on which the movie character was based upon.

Murder, armed robbery, rape, and a myriad of crimes all soared because the people who weren't allowed to own guns legally (the criminal types), still had theirs because they, of course, kept those weapons that they didn't have, because of earlier laws denying them the right to own weapons.

Meanwhile, the (PHRASECENSOREDPOSTERSHOULDKNOWBETTER.) honest folk were defenseless like so many (sheep) potential victms guarded by too few (sheepdogs) policemen to adequately protect them from the (Big Bad Wolves) armed criminals.

That's how it has been going so far in Australia and the UK.
