One of the more extreme government abuses of the post-9/11 era targets U.S. citizens re-entering their own country, and it has received far too little attention. With no oversight or legal framework whatsoever, the Department of Homeland Security routinely singles out individuals who are suspected of no crimes, detains them and questions them at the airport, often for hours, when they return to the U.S. after an international trip, and then copies and even seizes their electronic devices (laptops, cameras, cellphones) and other papers (notebooks, journals, credit card receipts), forever storing their contents in government files. No search warrant is needed for any of this. No oversight exists. And there are no apparent constraints on what the U.S. Government can do with regard to whom it decides to target or why. (…)
Poitras was not Snowden’s first choice as the person to whom he wanted to leak thousands of N.S.A. documents. In fact, a month before contacting her, he reached out to Greenwald, who had written extensively and critically about the wars in Iraq and Afghanistan and the erosion of civil liberties in the wake of 9/11. Snowden anonymously sent him an e-mail saying he had documents he wanted to share, and followed that up with a step-by-step guide on how to encrypt communications, which Greenwald ignored. Snowden then sent a link to an encryption video, also to no avail. (…)
Snowden had read Greenwald’s article about Poitras’s troubles at U.S. airports and knew she was making a film about the government’s surveillance programs; he had also seen a short documentary about the N.S.A. that she made for The New York Times Op-Docs. He figured that she would understand the programs he wanted to leak about and would know how to communicate in a secure way.
