Edward Snowden Says Disclosures Bolstered Individual Privacy

ATHENS — Edward J. Snowden, the former American intelligence contractor who leaked documents about surveillance programs, said on Friday that his disclosures had improved privacy for individuals in the United States, and he declared that “being patriotic doesn’t mean simply agreeing with your government.”

Mr. Snowden also said he was grateful for a campaign, led by human rights and civil liberties groups, calling on President Obama to pardon him, a move that would allow him to return to the United States without facing the prospect of many years in prison.
