There is not one Federal, State, or local law enforcement agency that utilizes the TSA's behavior detection voodoo program.
Most TSA BDO practitioners are two-stripers (lead screeners), but all TSA employees can exhibit Behavior Detection VooDoo tendencies. Call them out on this at all times.

^ If you see a two striper looking around with nothing to do, that's your guy.

Really? I would love to play Spot The BDO with these guys. It would just ruin their day. What to look for?
