London, England — Usman Ali has grown used to the routine whenever he passes through an airport on his way in or out of the UK.
As he walks to catch a flight, or shortly after touching down, he says he will be stopped by police and questioned without access to a lawyer and without the right to silence.
His laptop and mobile phone are examined and their data copied. He has also been searched, fingerprinted, obliged to give a DNA sample and photographed repeatedly.
Ali, a London-based Muslim cleric who travels frequently as part of his work for a charity delivering aid to Syrian refugees, says he has been stopped six times this year alone, and many times prior to that, often for several hours.
