The Ames (Iowa) Tribune reports local police put signs up on the doors of banks: "Due to a number of recent robberies within our community and to help ensure the safety of all concerned the Ames Police Department is requesting that you remove your hat and sunglasses before entering this financial institution."

"It's not mandatory," explains Cmdr. Jim Ronbinson, "but if a customer enters and leaves their sunglasses or hat on, what it might do would draw the bank employee's attention to this individual."

Why not just hang a sign that reads "Please place your sawed-off shotgun in the bucket by the door."
