The National Security Agency illegally collected tens of thousands of domestic emails before being stopped in 2011. The disclosure was made Wednesday in a newly declassified order from the Foreign Intelligence Surveillance Court, which oversees NSA spying. The FISC ordered the NSA to change its procedures after the agency admitted to wrongly collecting up to 56,000 emails a year over a three-year period. The NSA says the illegal email collection resulted from technical error, not deliberate snooping.
