It looks like he was a real pilot who was traveling personally. By tossing on a partial uniform he can travel with liquids. There is mention of someone already in the airport waiting for him. He used the KCM entrance and was picked for a random full inspection that sends you to the normal security. It appears that there he was picked out for some reason for a secondary inspection and he lost it. He mentioned being constantly randomed. TSA hates the KCM program because it was forced down their throats by Congress. Starting about 3 years ago they upped the random rate to pretty absurd levels. They are trying to kill the program.
