I see...the old reliable leftist theory that truth has an expiration date! Okay, show me three provable examples of where this inane sign stopped an atttack. I'll go first, and show three where it failed miserably. Monterey Park, CA. Texas Mall shooting. Colorado Springs nightclub. Your turn. Silly goose...the ONLY thing this sign does (or will ever do) is tell a whacko that they just found a shooting gallery...and the 'ducks' are waaaay unlikely to return fire!
