An interview with Sarah Harrison of Wikileaks: Julian Assange's associate and Edward Snowden's guardian angel. She spent the last four months with NSA whistleblower Edward Snowden and arrived in Germany over the weekend. "When whistleblowers come forward we need to fight for them, so others will be encouraged. When they are gagged, we must be their voice. When they are hunted, we must be their shield. When they are locked away, we must free them."
