Electronic Surveillance By US Law Enforcement Agencies Rising Steeply

hypnosec writes "According to data obtained by the American Civil Liberties Union (ACLU), surveillance of emails and other forms of Internet communications without warrants has increased substantially over the last two years. Documents, obtained by the ACLU, reveal that there has been a 361% increase in 'pen register' and 'trap-and-trace' orders between 2009 and 2011. The ACLU has appealed to Congress to bring in more judicial oversight in these warrantless orders."
