We can't even keep people from having heroin
and that takes flying in materials from Afghanistan and some serious processing before it's usable.
I understand the pain. I even understand (even if I don't feel) the visceral dislike and feelings of superiority towards people who own guns. But *think* first. Look at our attempts to ban drugs. Can anybody look at that and point to it as a model for *anything*?
Guns are easy to manufacture, transport, and conceal, and people want them. Can anyone name anything with those four qualities that has been successfully banned, anywhere? The Taliban was beheading anyone they found growing poppies and people still did it.
I know you're sick of the rhetoric, but please just consider it: stop focusing on the weapon, and focus on the person who used it. There's not a realistic way to get rid of the guns in the US. We need to find a progressive way to make sure only the right people have them. Handgun registrations and background checks seem to have done some good, or at least no harm: and (despite the infamy of mass shootings) homicides have dropped an incredible amount in the last 20 years. Extend that to long guns, maybe (even though they're essentially never used in crimes; it couldn't hurt). Require liability insurance like with cars.
The shooting happened in a gun-free zone, in a state with an assault weapons ban, using registered handguns. That should tell us we're looking at the wrong things.
