I was told at the airport that I would not be issued a civil penalty, why am I receiving a Notice of Violation?

TSA is unable to advise passengers/individuals at the time of the incident whether or not they will be assessed a civil penalty. When an incident occurs, the screening personnel forward the information to the TSA regulatory department to determine if a violation of the Transportation Security Regulations occurred. Once the investigation has concluded and it is determined that a violation did occur, the individual is notified by a notice of violation.
