I just went through "security" at MIA, and the guy in front of me was selected to go through the puffer machine. He did NOT set off the metal detector (and the TSO running the puffer asked the WTMD operator if he had), so I'm wondering why they made him go through the puffer machine.

Furthermore, they made him raise his hands while he was in the machine. This struck me as somewhat degrading - were it me, I'd have felt like I was being arrested or something.

Anyone care to comment? I'm sure you do...
