Australia has the strongest Gun Control Laws in the world, and bought back all the assault weapons from their owners 20 years ago. Now unless you are a member of a shooting club, or can show other just cause for owning a gun, you simply cannot purchase one. Of course making something illegal only affects those who abide by the law, so we still have drive-by shootings, armed holdups, and gang assassinations. Where do they get the guns from, now they are illegal? Simple: they buy the guns from overseas arms dealers and import them in the same containers they import Heroin, Crystal Meth and Cocaine in. Drugs are illegal too, it doesn’t stop them being available.
So if you enact Gun Control in the USA, don’t expect it to have any effect on criminals. Expect it to disarm the citizenry, who have the right to bear arms in the first place as a deterrent to tyranny, and a means of self-defence.
It might stop some psychotic serial killers from sourcing weapons, unless they think to buy them from their local Bikie Gang instead of from a legal gun shop.
Finally, even Australia’s gun laws would not have stopped Stephen Paddock from purchasing semi-automatic hunting rifles, then adapting them to be more or less fully automatic. He was an accountant, who retired a millionaire having never committed a single criminal offence in his entire life. He passed all the police checks required in Nevada, and would have done so here as well.
Americans should perhaps forget about Gun Control with all the constitutional bars to progress there, and instead make “Bump Stocks” illegal. I think even the NRA might support that.
