Craig Was Nabbed During Sex Sting Operation

A foot-tapping ritual was a common thread in many of the 41 arrests reported during a four-month airport restroom sting that snared Sen. Larry Craig.

An undercover officer would take a seat in a stall. Soon another man would sit in the stall next door and start tapping his foot, perhaps moving it closer to the officer's. The officer would move his foot up and down slowly. The suspect might then extend his hand under the divider between the stalls, sometimes repeatedly.

That would be enough to get the man busted....More?
