I'm retired military and I do not show TSA my military ID card.

First off everyone should receive screening that is respectful of each person. This is one thing that TSA should expend some effort on ensuring compliance by its employees.

Second, why should a phone call be needed when a person who desires to could show TSA their military ID or other evidence of military service when entering the screening line?

I think this announcement is positive proof that TSA does not treat everyone with dignity or respect but certainly will take a traveler to task if the actions of TSA employees are challenged.
