Telltale clue trips up criminal

When you watch shows like CSI, the thing that ends up helping the good guys catch the criminal is always something minute, like a drop of blood, a fingerprint, or a carpet fiber. In real life, it seems that sheer dumbassery helps the cops catch the crooks more often than not:

Police in Tennessee say it wasn't too difficult to find a man accused of walking out of a Walmart store wearing stolen jeans. He left his old denim behind — along with his wallet.

Officers in Gallatin say 20-year-old Dustin Matthew Marshall tried on the jeans and left without paying for them, but employees found his old jeans and wallet in a dressing room.

WTVF-TV reports police caught up with Marshall and a 19-year-old woman who was with him on Saturday night after a couple ducked out of a steakhouse without paying their bill.

Well, how was he supposed to pay? I mean, he didn't have his wallet with him.
