A fine line between Big Brother Is Watching, the Hitler Youth, and being a responsible and observant citizen. If he was in employee, he would probably have an ID around his neck. My concern would be if he were doing an audit of the crowded lines as well. Which lines were most crowded and at what time of day. Probably a good place for a suicide bomber to wait in line. Although it has been awhile, I seem to recall that they do check the tickets BEFORE you get in line where I am. Not sure if that is for security, or just to make sure you are in the right line!

If he were an employee performing a managerial audit, he wouldn't want to announce his identity with an ID around his neck. But your point about his observations of line lengths (which is an indicator he seemed to be interested in, hence his snapshot) would, as you say, be exactly the kind of thing a terrorist might be interested in.

Odd coincidence also the Nashville airport is just up the road from Murfreesboro (about 30 miles if memory serves) and that is the location of the planned TN mosque of note. Of course, the description of the photographer in question doesn't sound Muslim, does it?

Fun mystery...hope no trouble comes of it.
