on arrival Mexico (Cancun), all foreign flight crew (and only crew)diverted to a cordoned off 'pen" to await a customs search. The actual search seemed a perfunctory "going through the motions" took 10-15 minutes, conducted in full view of passengers passing by, duty free bottles clinking, none of whom were searched. Interesting that resources can be found for this while Mexico is in the grip of a full-blown drugs war although I haven't experienced quite such targeted unpleasantness anywhere else in the world. Anyone know what it's all about?
