Unless Poitras committed 40 different crimes or various crimes spanning 6 years, I think there's still something to be said about the rule of law based on what's been reported...which I think we both agree may not be the full story.
It's one thing to question/investigate someone in conjunction with specific, credible evidence as part of a larger, legitimate investigation; but having your devices searched or being questioned repeatedly at border crossings dozens of times over six years--especially for someone at least occasionally based in NYC who could have trivially been visited by law enforcement while home--seems a lot more likely to be part of an intimidation strategy than a legitimate investigation.
