What time is it? If it is between 9am and midnight then you should kill them. I have actually walked into a neighbour's house at 6am on a Sunday morning, turned the volume on their radio down, walked out without saying a single word and gone back to bed. I think I heard something along the lines of "You could have just asked you know" but I was half asleep.

Well it is not really hard to hook up a video camera for your front door. Then all you need to do a variation of one of the Spanish Death traps. See someone annoying on the video monitor, then simply pull out the latch and they fall 20 feet down onto wooden stakes pointed up. Or if you are feeling especially cruel stant the walls so it is impossible to climb up and then let them starve to death. Simple Diagram available on request.
