The worst was the rapist that knocked on people's doors and forced his way into the home, he was caught and a sister was confused as to why he had not attacked her, for the rapist had called on her door that evening...
The police asked him... He said "why that big tall guy stood behind her was the reason I didn't attack her..."
I heard a variation on this story. The sister had got into an elevator and the rapist got in with her. He couldn't attack her because there was a big tall guy next to her ... only there was no one else with her *dun, dun, duuuuunnnnn*!!!!
