Someone really should make a movie about all this.
Well, they sortof already did. It was called ...Death Wish.
Kitty Genovese was raped and stabbed to death in front of her apartment house in Queens New York in the 1960. It was later learned 37 people witnessed the attack. Not a single person called the police. The intervening men did well. Too bad someone’s thumb didn’t accidentally poke an eye out.
They could call it “Vigilante.”
