Glenn Reynolds on "gun-free" zones

Here:

It seems to me that we've reached the point at which a facility that bans firearms, making its patrons unable to defend themselves, should be subject to lawsuit for its failure to protect them. The pattern of mass shootings in "gun free" zones is well-established at this point, and I don't see why places that take the affirmative step of forcing their law-abiding patrons to go unarmed should get off scot-free.
