Not get away with per say but I could kill at least 50 of my neighbours before I got caught this afternoon if I wanted to.
Just go and wave to them through the window and when they let me in club them to death, then go next door and so on.
Im amazed it doesn't happen more often
We had a guy killing people in the UK a few years ago (Hungerford) he had an AK47 and only managed 17 I think, I could top that with a lump hammer.
