"“This is a more focused policy by the NSA. It aims to restrict upstream collection to only those communications that directly involve a foreign intelligence target,” said Margaret Hu, an associate professor of law at Washington and Lee University School of Law, in an interview with MeriTalk. “Although it is an important first step, in order to make this type of restriction permanent, it can’t just be a Federal agency’s policy. The NSA could change its mind at any time in the future and go back to collecting Americans’ emails about foreign targets.”"
