Sgt Lumpy, I think we are on the same page yes?
Glenn, I think I get the sentiment of that analysis. But it rubs me the wrong way to tell me I have to flee my own home from an intruder inside my home, especially one attacking me. I would think that if the attacker was persistent and pursued you would be putting yourself in more danger physically and legally by running out to the street. The way I see it is if you are on the street you have somewhere to retreat to, your home. When at home, you have no where to retreat to for your safety.
