From what I sent Jon Schneider (Schneider wrote the piece, he's not an airport official):

I just wanted to let you know that I think the Capital City Airport
shouldn't be pushing Robert Ball around. It seems from your
description that Ball was parked outside the airport grounds, and so I
can't understand how the airport security plan would have any force
there at all.

This is part of a very scary trend of forbidding U.S. citizens from
watching or photographing what goes on in public places. I worry for
the day when my children are taught to keep their heads down, not to
look directly at any of the officials, any of the vehicles, any of the
buildings, et cetera. Is Ball a suspected terrorist because he looks
too closely at the world around him?

This is not my America.
