I guess they aren't willing to learn. Australia had a mass shooting back in the 90s and then simply banned guns. There hasn't been a mass shooting again since then.

And the argument that criminals will still have guns doesn't really cut it. Because of the ban black market guns are so expensive. As Jim Jefferies says, if you are criminal that can afford $30,000 to buy an assault weapon ... then you have enough money you don't have to be a criminal

Don't get me wrong, I live in the USA and I do own handguns for target shooting. But if I had to give them up for the betterment of society it would not be a big deal.

Jim Jefferies is an Australian comedian who nails it.
