The whistleblower Edward Snowden and the journalist Laura Poitras have been named recipients of this year’s Ridenhour prize for truth-telling. The annual award is named after the late Ronald Ridenhour, who helped expose the My Lai massacre in Vietnam. Poitras has been one of the key journalists to report on Snowden’s disclosures over the past year. In a statement, the Ridenhour awards committee said: “Their act of courage was undertaken at great personal risk and has sparked a critical and transformative debate about mass surveillance.”
