NSA surveillance: A new door to court challenges?
FILE - This June 6, 2013 file photo shows a sign outside the National Security Agency (NSA) campus in Fort Meade, Md. A Brooklyn man serving a 15-year terrorism sentence hopes to challenge his conviction because the Justice Department only recently revealed to him it obtained evidence using one of the National Security Agency’s secret surveillance programs. The notification was a result of a new Justice Department policy after last year's disclosures by NSA leaker Edward Snowden and could lead to the reopening of many cases already closed.
