in most states someone who has multiple assault violations and a history of mental health problems can walk into a gun show with $700 and 15 minutes later walk out with a semi-automatic AR-15
"not technically an assault rifle" doesn't matter in the slightest, no one's impressed by this constant pedantry... yes, yes, it's an ArmaLite 15 and isn't technically an assault rifle because it's only semi-automatic. This changes absolutely nothing, mass shooters are essentially cosplaying during mass shootings with this thing because it looks like an assault rifle and it's easily accessible.
the proliferation of modern small arms is one of the worst things to happen in human history
