Man, we're really not seeing eye-to-eye. You really think Taylor's bf survived BECAUSE he shot at the cops? No-knock raids are shit but the police don't actually break into your house and literally shoot everything that moves. They break in with itchy fingers, shout some orders, and then start shooting at the slightest sign of resistance or non-compliance. Taylor died because her bf started shooting at the cops and the fired back. He just got lucky he didn't get hit.
And you're right that Jim Crow wasn't ended by fear of armed citizens killing too many cops, but by protesting, education, demonstrations, etc. The current BLM movement is likely going to create reform but not because citizens are shooting it out with the cops but because of the mass demonstrations that have taken place.
Guns to fight for freedom are needed in very precarious democracies and civil war situations. So yeah, it's great that the Kurds have arms, same with any other group that was fighting ISIS when it started spreading. But in Western democracies, rights are won on the streets, classrooms, congress and so on.
