Author of ‘Fast & Furious’ Book Blocked by DoJ Says Operation Worked as Designed

ATF Blocks Agent's 'Fast and Furious' Book (CNN)

(CNN) -- A federal agent's attempt to write a book with an insider's account of "Operation Fast and Furious" is being blocked by superiors because it could have "a negative impact on morale," the American Civil Liberties Union said.

John Dodson, an agent with the Bureau of Alcohol, Tobacco, Firearms and Explosives, was among several agents who claimed whistleblower status in order to provide information to Congress about the agency.

The controversial program allowed 2,000 guns to cross Arizona's border with Mexico beginning in 2009 with the intention of tracking them to criminal gangs.
