Did any see this documentary on five tv? - i managed to watch this though missed the first 20 mins. Was about ATF (Bureau of Alcohol, Tobacco & Firearms) agent William Queen, who went undercover in 'Operation Ivan' in late 90s for 2 yrs and joined up with the violent Mongols motorcycle gang in southern california. For the agent, the things he had to do, seen and heard, being under cover for 2 yrs started to take their toll, he was on the edge, scared for his life. Some of them had their suspicions early on he might be a cop, but as time went on, he managed to convince them he was one of them. Evently 54 mongols are sentenced to prison, other are charged. Would you want to be that agent with 1000 of other gang members on the search for you? After the being undercover for so long and adjusting to normal life had been hard for the agent, his children do not get on with him, and for their safety because of the case, are sent to another state (Florida), Billy lives in Texas, now retired in an undisclosed location. The Mongols are still strong as ever in southern california. EDIT; Mel Gibson may play the special agent in the movie 'Under and Alone' (2010), based on the book by the agent. Warner Bros were in talks originally with Antoine 'Training Day' Fuqua to direct. .
