Yes Aguila Blanca, you are right, I think I may not have read the statute entirely.
BUT it does say "or (2) such person is armed with explosives or a deadly weapon or dangerous instrument".
So what I read is that even if they're not after you, as long as they have a deadly or even "dangerous" weapon, it's considered home invasion.
Now, what the hell is considered "dangerous"? A sharp pencil? A dull knife? Couldn't just about anything be dangerous if used right?
