Christ, I wish people would think tactically.
You cannot possibly own the ground outside with multiple subjects from multiple angles. But let them come inside the house to get you, stack them in a hallway or on a staircase.
You are also much more legally covered. A guy walking up on your grass, trespassing. A guy walking into your door, home invasion and very, very hard to prosecute criminally.
Shoot up your own house, no big deal. Put rounds downrange throughout the neighborhood, bad juju.
The house is flammable.
Wait, you meant as the home owner...
