I like that it highlights that "I have nothing to hide" types really aren't thinking things through very well:
I work for a small nonprofit organization law firm in Washington, DC, that defends whistleblowers: the Government Accountability Project (GAP). Ordinary people come to us after they report appalling things in the places where they work and are dismissed, disciplined, or demoted in retaliation. They're hoping we can tell the world what they told us (at the very least) and get them their jobs back (at best). Most of our clients are federal government employees. We work with food inspectors, for example, who report animal cruelty in processing plants and toxic chemical additives to your food. Our clients are UN police officers who witness and report rape and sexual abuse by peacekeeping forces. Office workers and agents at the FBI and the NSA come to us to document gross waste and abuse. As do traders and risk managers who see pervasive fraud at multinational banks and FDA officials who report drug trials faked by pharmaceutical companies. At truly repressive institutions such as the World Bank, our sources remain anonymous, but they also contact us by phone and email.
As a result, at GAP, our emails are not boring, and we do not want the NSA collecting them, much less reading them. Since the Snowden disclosures, we ask our clients to meet us outside the office, downstairs, and around the corner at Starbucks. We have to talk face to face as if we were subversives. To be safe, whistleblowers facing retaliation must provide their evidence on paper now, not by email.
