Before today, the Liberty Dollar organization sold gold and silver coins. However, the FBI and especially US mint felt threatened by this "competition". So, the FBI raided the Liberty Dollar office and plundered all their gold and silver. They also seized information on what customers are to be shipped which coins that they ordered.

If you look through the documents posted its pretty obvious that indeed they really were plundered and wiped clean.
