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.
Are they being treated like a criminal in this case? Or are they merely being treated as requiring standard (not reduced) security screening?
I’m far more concerned where felons are denied the right to vote or to bear arms than I am with them having to stand in the same security line as most people.
