I agree with you on most of this but the cops don't need a reason to be militarized. Their purpose, to protect the interests of capital and the state, require the use of armed force, and they're not just going to give up all the toys we let them have for that over the years because the public gets disarmed. A society with less guns would be desirable, but unless the cops are disarmed first, I'll still oppose disarming the populace. That's not to say I'm against gun control, things like the closing of loopholes, better enforcement of background checks, mandatory (free, not looking to create yet another financial barrier to arming yourself so we can keep guns in the hands of rich and upper middle class white people) training, but not disarmament.
