20 Dead, 26 Wounded In El Paso Shooting

I got nothin'.
Crazy people + deadly weapons --> very bad.
Apparently the shooter is some kind of anti-immigration nut.
I have no idea what to do about this problem. Psychological evaluations in order to be able to purchase certain types of firearms? That's exactly the sort of thing a totalitarian state--or a progressive one, if there's a difference--would abuse. But the only thing standing between us and something like that is numbers--if mass shootings become sufficiently common, we will end up with another assault weapons ban, or something in that neighborhood.

[And another one in Ohio.]
