Pirating movies a threat to homeland security

Because I don’t want Glass to distract me during the movie, I turn them off (but since my prescription lenses are on the frame, I still wear them). About an hour into the movie (Jack Ryan: Shadow Recruit), a guy comes near my seat, shoves a badge that had some sort of a shield on it, yanks the Google Glass off my face and says “follow me outside immediately”.

This is a very disturbing ordeal that this man went through. I don't quite get why the Department of Homeland Security is tasked with movie bootlegging.

The way that he was treated during his 3.5 hour interrogation doesn't give me a warm and fuzzy feeling.
