A Justice Department audit has found numerous errors and possible breaches of the law in how the FBI uses its powers to access the personal information of U.S. citizens. The FBI can obtain telephone, email and financial records by issuing “national security letters” under the USA PATRIOT Act. Twenty-two possible breaches of internal FBI and government regulations were found out of a sampling of just 300 cases. Close to 20,000 national security letters were issued last year.
