Yeah I'm not opposed to the idea of gun control, but almost every proposal I see in the US is a knee-jerk reaction that is completely ignorant of the existing gun situation in the United States. I see people talking about concealing AR-15's being easier in Florida than a handgun. That's because SBR's already require a federal background check with a ~1 year wait and require tax stamp paperwork to remain with the firearm at all times and can't be moved between state lines without prior written approval from BATFE. And they're used in very few murders compared to handguns. But sure, your background check idea is doing something, so you can feel good while posting selfies with reflections of oncoming traffic in your sunglasses. Meanwhile you can make one from unregistered raw materials and minimal tooling and no one would ever know unless you chose to tell them. Let's use the same ideas we used to ban marijuana!
