When I went to Japan they had temperature sensors everyone had to walk through and if you had a fever they would flag you aside and make you wear a facemask to protect everyone else.

But making a registry of faces of every person who gets on a commercial airplane is just a bit nuts tbh. Security theater, while someone gets a fat contract.

Amendment IV

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

Will you give the feds your fingerprints and face to travel within your own state or to another state? That's the plan unless enough of us can raise a shitfit.
