Complaining about TSA screening is considered by the TSA to be cause for additional scrutiny.
Agent Jose Melendez-Perez told the 9/11 commission that Mohammed al-Qahtani “became visibly upset” and arrogantly pointed his finger in the agent’s face when asked why he did not have an airline ticket for a return flight.

“I think the idea that they would try to draw attention to themselves by being arrogant at airport security, it fails the common sense test,” said CNN National Security Analyst Peter Bergen. “And it also fails what we know about their behaviors in the past.”
