It appears that Strathclyde's finest have decided to, or have been told to, check the passports of passengers arriving at Prestwick Airport.
Passengers on domestic flights, that is.
Just what business it is of the police to be checking passports is anyone's guess. Checking the passports of international passengers is the job of the UKBA.
So why are they checking passports and what happens to those who refuse to play their stupid game? It's not an offence to travel without a valid passport on a domestic flight.
In my opinion they powers that be are just testing our 'compliance threshold'. If the sheeple happily play along with this, what's next?
