I was 3rd off the plane ATL-FLL and they had a drug dog at the jetway door.
After passing by, I stood off to the side to watch. The usual suspects, gang types with lots of jewelry, passed with no problem. Then the dog sat down when a 50ish DL Medallion member in a suite passed by.
The plane clothes cops came out of the crowd and took him to the side. In the terminal, they gave him a quick search and found about a joints worth of pot in his shaving kit.
