After being tagged for Secondary Screenings twice in a row I thought back over why I could have been selected. I determined that I was stressed out, fumbling around with my stuff, and looking around way too much. And I had some work IDs on a lanyard tucked into my shirt.
The next time I flew I removed all the metal items, carefully folded up coat, etc long before I was within visual of the checkpoint. I calmy and slowly approached the ticket checker and presented my boarding pass and DoD ID card. Did the same thing with the WTMD boarding pass checker who waved me right through without any hassle. Though my laptop did get wiped down.
