Also in 2008, district courts, with the help of the Government Printing Office (GPO), opened a free trial of Pacer at 17 libraries around the country. After activist Aaron Swartz, following an appeal by Malamud, downloaded about 2.7 million documents through a Sacramento library computer (less than 1% of the entire database, although the number has been stated incorrectly as 20% or 25%), to make them freely available to the public on Public.Resource.Org, the experiment was ended in late September 2008, with a notice from the GPO that the pilot program was suspended, "pending an evaluation." In October, a GPO representative said that "the security of the Pacer service was compromised." A FOIA request revealed later that the FBI had opened a full investigation against Swartz, which was dropped in April.
