Ep 560 Who was Darrin Kozlowski the man who infiltrated the Vagos, Mongols and Warlocks Motorcycle Clubs

:"On and off for almost 20 years, I investigated and infiltrated outlaw  motorcycle gangs as an agent for the U.S. Bureau of Alcohol, Tobacco,  Firearms and Explosives. I wasn’t the only agent to go deep undercover,  and I don’t claim to be the best. But the work I did took a lot of bad  guys off the streets. I infiltrated the Warlocks in West Virginia in a  case that took me up and down the East Coast—Florida, South Carolina,  Brooklyn, the Bronx Dan Kozlowski
