I had some time off so I have been binge watching Gangland Undercover. I read the book so I looked up the show. The episodes are free on YouTube. (Except I can't find the last 2 which really sucks). It's based on the real life story of Charles Falco, an informant who infiltrated the Vagos in California, then once in the witness protection program got involved with the Mongols and then the Outlaws, all the while working for the ATF. Who knows how accurate it is, but if you enjoy shows about MCs, check it out.
