To a degree, I’ve become a nihilist about much of this. There isn’t a strongly majority taste for making guns more scarce or harder to get. There isn’t much way to force people to be hyper responsible en masse. They never have been and never will be.
And we have a society that both fetishizes some kinds of violence and perpetually overblows how much of a risk it is in daily lives. So folks will probably get shot senselessly somewhat often. You’d have to take out some of the major contributors to shift that, and I don’t think we really want to.
(there’s also obviously the constitutional right thing, which is its own sticky space)
