The TSA is allowed to lie in its responses to Freedom of Information Requests. Its court-granted ability to lie to the public it nominally serves isn't limited to sensitive issues, either: they're allowed to pretend that they don't have CCTV footage of their own officers violating their own policies, even when they do.
U.S. District Judge Joan A. Lenard granted the TSA the special privilege of not needing to go that route, rubber-stamping the decision of the TSA and the airport authority to write to me that no CCTV footage of the incident existed when, in fact, it did. This footage is non-classified and its existence is admitted by over a dozen visible camera domes and even signage that the area is being recorded. Beyond that, the TSA regularly releases checkpoint video when it doesn't show them doing something wrong (for example, here's CCTV of me beating their body scanners). But if it shows evidence of misconduct? Just go ahead and lie.
