I recall an elderly French traveler doing this in the US shortly after the excessive policies started. The TSA policies are so ridiculously over the top and have not made us any safer. They have protected American flyers from dangerous cupcake icing They harass youngsters right up to seniors without regard for common sense. Even worse, the porno-scanners are not effective beyond lining the pockets of lobbyists like Chertoff. If anything, it's a surprise that this doesn't happen more often.
With the latest mission creep by the TSA, they're now doing searches on buses, trains and yes, even roads. What's also unfortunate is that the political class is too afraid of changing course from this bad policy for fear of being called weak on terrorism. What a sad joke.
