Andrew Grossman has more on the case against Gibson Guitars:
Gibson’s crime, according to an affidavit supporting the search warrant, was the illegal importation of Indian-grown ebony veneers, intended for use as fret boards. A hardwood prized for its appearance and durability, ebony is sustainably raised by certified growers, and Indian law doesn’t bar its harvesting or export. What Indian law does require is that ebony veneers be finished within the country, by local labor, to a thickness of less than 6 millimeters. Gibson’s wood, it happens, was a bit thicker — nearly a full centimeter.
On that basis, U.S. Fish and Wildlife Service agents invaded Gibson’s facilities, bringing its operations to a standstill.
(*A commenter correctly points out that this was a raid by armed federal agents, but not a SWAT team.)
