Alerting the bad guys
What the sign says: “This is a gun-free zone.”
What the sign means: Attention all terrorists, nut cases and ticked-off psychos. For your convenience, we have disarmed all law-abiding citizens in this building, which means you will be free to shoot as many people as you can without fear of being shot at for the next five to 15 minutes, when the police arrive.
Gun control: Simple solutions for simple minds.
