"The only area of legality that would concern me would be self defense"
On a fairly related topic, I'm reminded of a story told by friends 40 years ago. They raised Saint Bernards. A police officer had come to their home for something or other and while chatting, they posed the hypothetical question: "What do we do if someone breaks into our backyard." The officer went to the back door, opened it and was met by their male dog. The dog placed both front feet on the door jamb and barked. The officer closed the door, sat at the kitchen table, and lit a cigarette. Seems like he needed 3 matches, but I'm not sure about that point. His advice was "Bury the body and don't tell anyone what happened."
