That’s the only message I can deduce from the announcements that they’ve started running in hotels. The “suspicious person” shown in the video would appear, to any bystanders, to simply be getting something out of the trunk of his car. So I guess that anybody driving, or at least anybody carrying things in their trunk, is a potential terrorist.
Security theater again, obviously. In this case, though, I hope that a lot of people do follow through and report everybody they see opening up the trunk of a car. Considering that these messages are playing at motels, that should keep the DHS investigators so busy they won’t have time to screw us up any further.
