Sounds like they were Eric Holder's DOJ storm troopers.

On August 24, 2011, around 8:45 a.m. CDT, agents for the federal government executed four search warrants on Gibson’s facilities in Nashville and Memphis and seized several pallets of wood, electronic files and guitars.
The Federal Department of Justice in Washington, D.C. has suggested that the use of wood from India that is not finished by Indian workers is illegal, not because of U.S. law, but because it is the Justice Department’s interpretation of a law in India. This action was taken without the support and consent of the government in India.
Gibson has obtained sworn statements and documents from the Madagascar government and these materials, which have been filed in federal court, show that the wood seized in 2009 was legally exported under Madagascar law and that no law has been violated.
