You guys are loonies!
Think about this:
If you shoot some guy who is trying to run away with your chainsaw (and really have you ever tried sprinting carrying a chainsaw?) think of the paperwork. Here there will automatically be an inquest. You will need a lawyer. You will lose days of work time telling your story.
Then: How much do you practice? Have you tried shooting a running person? Have you practiced over and over again, evaluating the scene to make sure that the shots that miss your target don't take out a kid in the yard further along?
Look at the stats for kids who get hurt by household guns.
If you are going to carry a deadly weopon, I want you to fire 500 rounds a month target practice on the kinds of range the police use where scene evaluation is critical for 20% of those.
Stay out of my town.
