Flying used to be a great way to escape a crime that was just committed. By knowing the name and id of every traveler, we can stop criminals from fleeing their crime scenes.
But if they have just committed a crime the system wouldn’t know to look for them, would it?
However assuming that it takes a while for the suspect to decide to skip town, it’s perhaps useful. The next question is whether it’s worth spending the money on these machines, hiring people to run them, and inconveniencing the innocent travelers (presumably 10^9 X the number of perps collared) is worth the occasional arrest. Ignoring false positives of course. And especially when there are plenty of other ways to skip town.
I have a separate problem with scope creep.
But thanks for suggestions use case that can actually be considered. Is this reason ever used as a justification for the TSA?
