Gun free zone liability act
Alan Korwin reports that bills have been introduced in AZ and GA to make entities that declare "gun free zones" liable for any harm caused by impairment of self-defense.
Update: I'm informed the GA bill is from 2003; there is no such bill pending there now.
Via Instapundit, who has in the past suggested you could get the same result under common law. It might be clearer now -- I mean, every mass killing I can remember occurred either in a gun free zone, or a place where the killer would expect no one to be armed (an Amish schoolhouse, a church -- the killer in the Colorado cases may have *thought* churches were gun-free in that state). And every mass killing that was stopped short was stopped by armed civilians, not by LE.
Also via Instapundit, SayUncle has an impressive list of armed civilians vs. mass killers.
