I hope this last tragedy will actually prompt a change in everybody's mind. and therefore an action under the form of a law, where NO ONE can own more than a gun, and background yearly checks to make it such a pain in the ass that takes ALL the "fun factor" out of it. Violence cannot be associated to fun. And weapons are the ultimate violence tool.
Crazy nut jobs are all over the world. Why here in US they manage to get a bulletproof vest and 3-4 automatic rifles? On regular basis???
You can't get an automatic weapon without a class 3 weapons permit, which is very expensive and hard to get. Not very many people have it.
I'm not a huge fan of putting further regulations on long guns. Maybe handguns though. And I'm all for improved background checks.
