It seems Dateline sent reporters to the Defcon IT Security convention, an event I personally know nothing about but it sounds like it’d be full of people who still differentiated between “hackers” and “crackers” and get pissed if you misuse the terms. Now, reporters are allowed in the convention, but they have to wear ID tags identifying themselves and their employers, and get permission from anyone they photograph.
Of course, Dateline was there “To Catch a Hacker”. They wanted to catch someone admitting to illegal deeds and then confront the con’s organizers with the tape. A guy dressed like a tree may or may not have been also involved. This being a convention of security experts, who play “spot the federal agent” as an annual event, saw her coming a mile away, and called her out on stage. They again offered her press credentials, but she probably didn’t hear that as she was hounded back to her car by camera-wielding nerds.
Sadly, at no point did anyone dress like a tree.
