EFF has filed the final brief in its dispute with the government over evidence preservation in Jewel v. NSA, one of our ongoing lawsuits against mass surveillance. As the brief explains, the government has admitted to destroying years of evidence of its mass spying, and this destruction continues today. In fact, at an emergency hearing in June, the government claimed that it was incapable of complying with a court order to preserve evidence relating to the mass interception of Internet communications it is conducting under Section 702 of the FISA Amendments Act.
