Even worse - this is one of the more bizarre complaints threads as it is even harder to understand what is being complained about. Op is complaining because he was pulled aside to have documents verified??? Whether systematic or random or targeted is not too relevant - but one complains about being checked??? And suggesting too that this has anything to do with UA or US? Anyone who has travelled enough, internationally, at one point or another would have had similar experience in a non-US country flying an airline that was not UA. Some pax have even been taken off a boarded plane to be checked a third time. What next will we be complaining about?

Bigger question is what the OP regards as indecent countries...
