There was a movie once about a society where on the police and the military had weapons.
I’ts called “Shindlers List”.
Kind of. Left out of the movie, likely due to the producers political positions, was the fact that Schindler amassed arms for his works, and in at least one instance is said to have sent out a group to kill a difficult SS officer. Obviously the workers at his factory couldn't have prevailed, but they could have defended themselves, possibly allowing some to survive.
