The government may have breached its settlement with a former federal agent who claims the Hell's Angels burned down his house in retaliation for his successful infiltration of their motorcycle gang, the U.S. Court of Federal Claims ruled.

Quote from the article:

As an agent for the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), Jay Anthony Dobyns was the lead undercover agent in "Operation Black Biscuit," the first operation to successfully penetrate the Hell's Angels motorcycle gang. The 21-month undercover operation from 2001 to 2003 led to the indictment of more than 16 Hell's Angels members. But Dobyns' relationship with the ATF deteriorated after his identity became publically known. Hell's Angels members threatened him with violence and death, he said, but ATF did little to protect him or his family. When he complained to his superiors, he said the ATF launched a smear campaign against him, attacking his personal and professional reputation and claiming he wasn't fit for his job.
