Over on Boing Boing Gadgets, our Joel's spotted a rara avis from the criminal underground:
A Consumerist reader found a card skimmer on a WaMu ATM. He ripped it off and reported it to the police and the bank. The police said they'd never actually seen one in real life.
I always check for card skimmers at the ATM by smashing the front repeatedly with a sledgehammer, starting with the camera.
