And into what little database are my deets being entered for eternity by using either of these options, and to whom does the visibility to this data go?
I can see it for Part C, but why A and B? If someone's been charged and done whatever was required to be free enough that they can fly, then that should be the end of it. Especially things on that list. If treason isn't enough for the government to execute them or lock them up and throw away the key, then it shouldn't matter to the TSA.
If you can’t see how felony conviction for having illegal explosives might reasonably preclude you from reduced security screening, I’m not sure anything I can say will convince you.
If you can't see how the government continuing to treat someone like a criminal after they've paid their debt to society is wrong, I'm not sure anything I can say will convince you.
Can you not buy anonymous tickets, for example at a counter in the station or from a machine?
There are still enough machines that take cash that this is a practical option in most of Europe. Buying a ticket in advance works, but requires a trip to the station.
