Fuck me, that's intense and I hadn't even gotten to the video. What gun is that? It looks like what I'd use in a Call of Duty game, a SCAR or something like that.
We had some reform in NZ after the Aramoana Shooting (14 dead, our country's worst I believe?) - some firearms were reclassified to minimize the chance of them being used in that manner. A surprisingly good movie came from it too.
I guess I just don't grasp the culture around firearms that appears to be in the States. I know people who own firearms for hunting and pest control, but never for personal defence - they're always locked up and dismantled to some degree until they need to be used. Is it where people are thinking "Well someone could use their weapon against me, so I should be armed to negate that if possible"?
It both fascinates and terrifies me.
