In 1986 Cooley became disgusted by the people he worked for after being given a contract to kill a police officer. He approached the U.S. Justice Department'sOrganized Crime Strike Force and declared, "I'd like to help you destroy the First Ward. I want to help you destroy Pat Marcy." He proceeded to work undercover as part of an FBI probe known as "Operation GambAt" (for "gambling attorney"). His work ultimately sent 24 men to prison, including Outfitmobsters, politicians, police officers, and judges.
