One other thing to keep in mind: our instructor told us that if you were in a self-defense situation and used a weapon that was somehow illegal (i.e. no CHL and you were in a public place carrying it on your body), the carry-infraction would be separate and not affect the shooting itself. In other words, you wouldn't be found guilty of murder or something just because you were carrying illegally. You'd be judged on the self-defense act separately, and judged on the weapons charge separately. I didn't state that very well, but hopefully it comes across. This can have huge consequences for some folks who decide to arm themselves for self-defense even when the laws of the land restrict that right.

And I'm sure someone will correct me if I'm wrong.
