That's CBC News referring to Laura Poitras, the journalist and filmmaker behind the Oscar-nominated documentary Citizenfour, which offers a look at NSA whistleblower Edward Snowden's first meetings with journalists.

Poitras, who's been detained and questioned by federal agents dozens of times since she began working on films exploring the post-9/11 era, spoke with CBC's Amanda Lang about the film, Snowden, and post 9/11 violations.

In the interview published Wednesday evening, Poitras said that when she first received anonymous contact from Snowden, she said she realized if the shocking claims proved to be true, then this mysterious person was taking enormous personal risks.
