I think this piece is fluff. According to the original article, the story unfolded a bit differently. A suspicious cop with no 'Aesthetic Values' asked a photographer for his license. This not being Nazi Germany, the photographer was offended and talked back, then later publicly complained. He was not detained as in hauled to a police station, but rather not allowed to leave before the policeman assessed why he was taking photos in a refinery. The cop did his job and the journalist his. No story here, other than the cop trying to be a bully and threaten to use terrorism charges if he feels like it. This is business as usual it seems anyways.

    1 After running Wolff's driver's license, Kahn left the scene without ordering Wolff to desist.

    2 Legally, a police detention has occurred when "a reasonable individual" in that circumstance would be believe he or she is not free to leave
