The defense against the government issue is probably the best reason, but also in many ways the silliest.

We have drones that can blow up your house from so far away you can't even see them. Not to mention more conventional weapons like tanks, high powered sniper rifles, mortars... basically if the military were turned against our own people we'd be fucked no matter how many guns we have because the military has better, bigger and more advanced weaponry.

I believe there are reporting mechanisms but they don't result in an inability to buy guns, they just get watched by the police or FBI... who in this case fucked up and didn't follow procedure.

But more importantly: I don't think Republicans in this country would even allow your suggestion. They'd claim it steps on their gun rights and that false reporting would be used to take guns away from law-abiding citizens.

That's why I challenged conservatives to come up with something. They won't accept anything liberals propose, so it's on them to fix it.

I also never see any effort from them to try and fix it.
