From EPIC.org:
EPIC filed a Freedom of Information Act appeal, seeking disclosure of NPSD 54, the classified Directive that describes a National Security Agency program to monitor American computer networks. EPIC submitted the original request to shed light on the extent of the federal government’s surveillance of civilian computer systems, but the agency refused to disclose the document. EPIC’s appeal warns that the NSA’s improper withholding of the Directive “flatly contravenes” the President’s policy on open government and “explicit FOIA guidance promulgated by the Attorney General.” EPIC further stated, without public disclosure of the Directive, “the government cannot meaningfully make assurances about the adequacy of privacy and civil liberties safeguards.”
