Came through DEN yesterday and saw some electronics/radar? I-don't-know-what contraption set up facing the center entrance to the main terminal from the east terminal. A lot of TSA and black t-shirted homeland security types were standing around looking very important. One even had 4 cell phones on his belt!

As the whole affair was very public (it's hard to look so important without doing it publicly) I asked one of the TSA what they were doing. He brushed me off with, "We're doing the protocol!" Now I'm pretty sure that the buffoon didn't even know what the word means in the context in which he used it, so I just moved on.

Anyone know what they were up to?
