Don't look over your shoulder

My sister, who works at the Federal courthouse in Denver, sent me a link to this story about an employee there who was arrested for spilling coffee in the X-ray machine. It's hard to say if the spill was accidental or intentional, even though the video captures the action from two angles. As my sister explains, everyone has to go through security, even employees who have been there for years and years. They have to show their IDs (to guards who know them well) and pull out cell phones, cameras, and other electronic devices. Drinks have to go through the machine too. I guess this woman had had enough.

The surveillance cameras at the courthouse made me think of the great book I just finished reading, I Am the Messenger, by Markus Zusak (Fiction Z89i). Ed Kennedy has apparently been appointed a "messenger" by someone who is clearly watching his every move. He gets his cryptic orders on playing cards. Other actors are sent in to not-so-gently get him on track when he strays from his main task. Who is watching and why?
