Further confirming and providing more details about a story first reported here and later confirmed by the New York Times, Ted Hesson and Kristina Cooke of Reuters report that more than 31,000 records of domestic airline reservations obtained by the Transportation Security Administration (TSA) through its Secure Flight passenger surveillance and control system were passed on by the TSA to Immigration and Customs Enforcement (ICE) in the first year of the Trump 2.0 Administration. More than 800 arrests by ICE during that time were based on Secure Flight data.

The TSA has exempted Secure Flight records of domestic air travel from the provisions of the Privacy Act that would normally entitle each traveler to obtain, on request, an “accounting of disclosures” showing what information about them was disclosed by the TSA to which other agencies or third parties. So there is no way for you to find out whether the TSA has provided ICE with your air travel plans, so that ICE can arrange an unwelcoming party for you at the airport on departure or arrival or while changing planes. You have to assume that ICE has the details of all of your planned air travel in the U.S.

The arrests at airports reported to date all appear to have been of non-U.S. citizens. As we noted when we first reported on the additional of immigration lookouts to the Secure Flight ruleset, the TSA has long wanted to expand its airport checkpoints into all-purpose law enforcement checkpoints by checking all airline passengers against the FBI’s aggregated NCIC database of wants and warrants. That still doesn’t appear to be happening, but we have no confidence that the TSA will confine its activities within Constitutional limits, especially in an area where it has exempted itself from accountability.

Please let us know if you hear of U.S. citizens being arrested at airports on outstanding warrants, especially if there is no obvious way police would have known of their travel plans without having been tipped off by the TSA based on airline reservation data.
