Secret Quiet Skies surveillance program tracks citizens not suspected of wrongdoing:

Federal air marshals (FAMs) told the Globe that the program is a waste of taxpayer dollars and actually makes the U.S. less safe as they are not working on “legitimate, potential threats.” Many are not even sure if it is legal, but the TSA told the Globe it is part of its “mission to ensure the safety and security of passengers, crewmembers, and aircraft throughout the aviation sector. As its assessment capabilities continue to enhance, FAMS leverages multiple internal and external intelligence sources in its deployment strategy.”
But John Casaretti, president of the Air Marshal Association, said, “Currently the Quiet Skies program does not meet the criteria we find acceptable.” He added, “The American public would be better served if these [air marshals] were instead assigned to airport screening and check in areas so that active shooter events can be swiftly ended, and violations of federal crimes can be properly and consistently addressed.”

I almost understand the false sense of security current airport practices provide the average Jane and John Doe.
But super secret security theater busywork?

Be nice with what you write.
