So it's like your husband will just shoot them, and leave one by one, like in Katyn, leaving massive pile of boddies there. After like 50 kills there should be a wall made of boddies, and after few days it will stink that hobbly, that your daughter's boyfriends will stop in middle of the hallway, and turn back running towards your husband, and we will finally see some kills.
