Violence was a moderating factor when people on each side were equally armed, and number was a deciding factor.

Nowadays you could squash an uprising with a few operators piloting drones remotely.

Flying a drone around is easy. Identifying who is on the in group and out group and then moving them is the hard part.

I’m not sure you have really thought out what the drone part is meant to do. Militaries gave outgunned populaces for decades at this point. You don’t need drones to kill civilians.
