“It’s true that TSA’s physical screeners are embarrassingly bad at their jobs, failing to notice 95% of threats in tests by Homeland Security. But TSA also has Behavior Detection Officers. These super agents can spot terrorists just by looking at them. Now, thanks to a leaked TSA checklist (and scorecard) of suspicious behaviors, you can too! The document shows 92 different behaviors that can flag you as suspicious — such as being too happy (or too sad); having ‘sweaty palms’ or ‘rubbing hands’; ‘arriving late’ and ‘body odor’; ‘gazing down’ or ‘open staring eyes’ — to which ‘points’ are attached. If you score six or more points, you win a trip to enhanced screening and a police interrogation.”
