ATF agent likely to win one against ATF management
A Federal Court of Claims judge calls the government's conduct "disturbing" and "wrenching". There are other reports that the judge said it was the worst case he'd seen in all his years on the bench.
Agent Jay Dobyns spent years infiltrating the Hell's Angels, until his cover was blown and he started getting death threats from folks whose threats mean something. He'd fallen into disfavor, and BATF did nothing. An arson attack burned his home ... and the agency tried to frame him for it. The trial revealed an email where one supervisor emailed another about hiding information from higher level management, and assured the other that "I can hide the ball with the best of them."
