LOL i was just thinking of Chris Rock's solution to these sorts of shootings. Make bullet's cost $5000 each. His comedy sketch on that one is pretty good.
But what if he broke into my house in the middle of the night, and I had no idea what he was up to? I would rather put him down than risk him killing anybody. (This is where a gun with very strong tranquilizers would come in handy.)
most likely just shouting "what the **** do you think you are doing" would make the burglar run away with incredible speeds.
But yeah, you never know. Of course your family is more important than some random guy. Again, taser would be a good option. Definitely brings him down but doesn't cause any permanent damage.
