Once in Rivet City, I was caught stealing a tidbit and all of a sudden the guard was after me. Since I didn't want to fight, I ran aimlessly through thew corridors since I often get lost in RC, and picked the lock to a random room and fled inside for cover. Since I'd taken damage, I stole all of the food from the shelves and ate it, before killin a guard who had ran inside. Then, a resident ran at me, and I blew his head clean off in VATS, with his decapitaded corpse now laying in the middle of the hall. Then, out of nowhere, a resident came and said "God bless you" before walking past. Everyone had suddenly stopped being hostile.
The headless corpse was always just laying there every time I visted RC after then.
Plus there was this one time with my freind, when we were targeting a Supermutent with a shotgun in VATS for multiple attacks. After the first shot, it just stopped shooting and showed the Supermutant just standing there shooting at us for about a minute before it actually let us fire again.
