This sounds like a setup to get people to reveal their plans to the government when they send Blackwater after us.
Not true at all. From what I've seen of Blackwater, they'll open fire on your home with every thing they've got and when your home is in smoldering ruins and you are most assuredly bloody pulp, they'll then claim that you
actually started the fight.
In all seriousness - your plan sounds like a good one. I always wonder why self-defense usually means running away. Without seeing your home, it sounds like your only option is to stand your ground and wait for the police to arrive.
