How many young people have to die senselessly? How many lives have to be ruined before we realize the right to bear arms doesn’t protect us from a government equipped with stealth bombers, predator drones, tanks and nuclear weapons?
Last time I checked, parking a stealth bomber on a street corner, or nuking your own country, wasn't how a police state was run. Tanks, drones and helicopter gun ships can't go house to house kicking in doors either. You need an unarmed populace and boots on the ground for that. High powered rifles in the hands of the citizenry, are still a legitimate threat to such an environment forming.
