An FBI agent who pleaded guilty to drunken driving has sued the maker of his pickup because it caught fire after he passed out behind the wheel. Robert Clymer, who was involved in a high-profile investigation of the Crazy Horse Too strip club, had a blood-alcohol content of 0.306 percent, nearly four times the current legal limit, and was unconscious when Las Vegas firefighters pulled him from his burning truck on Jan. 29, 2005.
