Laura Poitras profile in NYTimes
“They took my bags and checked them,” Poitras said. “They asked me what I was doing, and I said I was showing a movie in Sarajevo about the Iraq war. And then I sort of befriended the security guy. I asked what was going on. He said: ‘You’re flagged. You have a threat score that is off the Richter scale. You are at 400 out of 400.’ I said, ‘Is this a scoring system that works throughout all of Europe, or is this an American scoring system?’ He said. ‘No, this is your government that has this and has told us to stop you.’ ”

Laura Poitras has for some time now been working with quiet, diligent, and steadfast determination to document the American Survielance system. It was Poitras, along with Guardian journalist Glenn Greenwald who filmed the now infamous Hong Kong Snowden interview.
Today's NYTimes sheds some light into some of her privacy methods:
...In addition to encrypting any sensitive e-mails, she began using different computers for editing film, for communicating and for reading sensitive documents (the one for sensitive documents is air-gapped, meaning it has never been connected to the Internet).
Poitras began taking steps to protect her data, asking a traveling companion to carry her laptop, leaving her notebooks overseas with friends or in safe deposit boxes. She would wipe her computers and cellphones clean so that there would be nothing for the authorities to see. Or she encrypted her data, so that law enforcement could not read any files they might get hold of. These security preparations could take a day or more before her travels.
...some of her history as a filmmaker (she's been making films since 1992), and her appropriate concern with being stopped at airports.
After being detained repeatedly, Poitras began taking steps to protect her data, asking a traveling companion to carry her laptop, leaving her notebooks overseas with friends or in safe deposit boxes. She would wipe her computers and cellphones clean so that there would be nothing for the authorities to see. Or she encrypted her data, so that law enforcement could not read any files they might get hold of. These security preparations could take a day or more before her travels.
