Only Government apologists can trot out the argument that such a profound and gross mistake like questioning the rights of citizens to enter their country can be a simple mistake. That was a stupid retarded mistake and if the supervisor were't there, the pax may have been in trouble. Governments are for the people, not rulers of the people. If a Government lackey makes a mistake, they should pay for it. If they don't like it: they can always go and do something else: dog catcher for example.
