To ensure traveler's security, transportation security
officers (TSOs) may determine that an item not on the
prohibited items chart is prohibited. In addition, the TSO
may also determine that an item on the permitted chart is
dangerous and therefore may not be brought through the
security checkpoint.

So if that TSO didn't get layed last night, he'll confiscate my stuff with
no explanation at all?

Another reason to stay out of that contry of madmen.
