An internal audit has revealed that the NSA violated both legal rules and privacy restrictions thousands of times each year since 2008, leading to the unauthorized surveillance of American communications. According to the 2012 report, there were 2,776 violations in the previous 12 months alone. A "large number" of calls placed from Washington DC were intercepted when its area code was confused with that of Egypt. Another document shows how NSA analysts are trained to avoid giving "extraneous information" to their "FAA overseers" when they want to target an individual. In 2006, EPIC wrote to the Senate Judiciary Committee regarding instances of intelligence gathering misconduct by the FBI that were uncovered through EPIC's Freedom of Information Act requests. EPIC is currently petitioning the NSA to suspend its domestic surveillance program pending a public comment period. EPIC has also filed a petition with the U.S. Supreme Court challenging the legal authority of the FISA Court to authorize the NSA's program.
