About that 'Australian Model of Gun Control',

not as wonderful as the gun bigots like to paint it:
Clinton and Obama tout a 1996 "gun buyback" that was actually a compensated confiscation of self-loading rifles, self-loading shotguns, and pump-action shotguns in response to the Port Arthur mass shooting. The seizure took around 650,000 firearms out of civilian hands and tightened the rules on legal acquisition and ownership of weapons going forward.
And how did that actually work?
Other researchers agree. In a white paper on the results of gun control efforts around the world, Franz Csaszar, a professor of criminology at the University of Vienna, Austria, gives examples of large-scale non-compliance with the ban. He points out, "In Australia it is estimated that only about 20% of all banned self-loading rifles have been given up to the authorities."
Guy I know heard from a friend in Australia a few years back that when the confiscations happened, there were areas where, for a month or so, you couldn't find 6" PVC pipe; it'd all been bought up.  And most of it wasn't used for plumbing.

And the result of all this crap, as usual, is screwing with honest people and causing- maybe- minor difficulty to bad guys.
Just days ago, Australia's Peter Dutton, Minister for Immigration and Border Protection, and Michael Keenan, Minister for Justice, held a joint press conference to announce "We don't tolerate gun smuggling in Australia and we know Outlaw Motorcycle Gangs are engaged in it. We have been keen to send the strongest possible message from Canberra that we're not going to tolerate people smuggling in guns or smuggling in gun parts. You'd appreciate that even one smuggled gun can do an enormous amount of damage."

When politicians announce that they don't tolerate something, it's a fair bet that the something is completely out of hand.

"Police admit they cannot eradicate a black market that is peddling illegal guns to criminals," the Adelaide Advertiser conceded a few years ago. "Motorcycle gang members and convicted criminals barred from buying guns in South Australia have no difficulty obtaining illegal firearms - including fully automatic weapons."
So, the result of all this is screwing with honest citizens, increasing control over them, and causing (maybe)slight difficulty to bad guys, and creating a new black market.  And don't forget the 'make it yourself' industry this created.

Yeah, the Australian and British models, just the thing we need to follow.
