While Clinton, Obama and your local gun bigots applaud the Australia way,

point out to them just how badly it's actually worked:
Despite Australia’s strict gun control regime, criminals are now better armed than at any time since then-Prime Minister John Howard introduced a nationwide firearm buyback scheme in response to the 1996 Port Arthur massacre.
Shootings have become almost a weekly occurrence, with more than 125 people, mostly young men, wounded in the past five years.

While the body count was higher during Melbourne’s ‘Underbelly War’ (1999-2005), more people have been seriously maimed in the recent spate of shootings and reprisals.

Crimes associated with firearm possession have also more than doubled, driven by the easy availability of handguns, semi-automatic rifles, shotguns and, increasingly, machine guns, that are smuggled into the country or stolen from licensed owners.

Of course, you have to consider one thing about the effect of Australian law: it made it a lot harder for honest citizens to own a gun, and restricted what kinds are allowed, which is what a lot of the clowns were actually after.  So in that sense, it's succeeded.

All the crime?  Well, that's just excuse for more laws and more restrictions.  Which they also really, really want.
