One of the things that continues to boggle me about the long lines at airport security stations is the security risk created by those long lines. Think about it - if someone wanted to create an incident, isn't a huge line of immobile people a target? That's why the "tomato juice" story from yesterday caught my eye:

People were welcomed to Terminal D of LaGuardia Airport with a line so long, it was difficult to tell where it began, or where it ended - all because someone spilled tomato juice on an x-ray machine.

So in short, a team of two people could create havoc: the first one "accidentally" takes out a scanner. The second one waits for the line to get big, and uses a bomb. If and when something happens, I wonder if anyone will question the ruleset that created the problem.
