I don't cheer when anyone guns anyone else down.
However, if the word "intruder" describes someone coming into my house, without my permission, where my wife and baby daughter sleep -- you bet, I want that intruder to understand full well that he is playing with fire.
A knife wielding burglar? I don't want to engage in hand to hand combat, and I don't want a knife to wife's throat while I'm ordered around the house.
This shit about characterizing intruders who aren't packing heat as sort of innocent, and nothing to fear, man, I don't know where this comes from. If someone breaks into someone else's house without permission, they are committing an aggression -- a violent aggression - and the homeowner has the right - and I would add the obligation - to protect himself/herself and their children/family members.
