Passport exit checks are a smart but long overdue strategy to combat the illegal movement of people. When criminals know they will be checked going " the other way " , this will hinder their heretofore free movement into and out of the UK. Check everybody. Profile as needed. Inquire , question , interrogate as necessary. We might not collectively realize it , but to many crazy religious lunatic nut-jobs , we are at war. We must protect ourselves and this island nation , no matter what short term pain or inconvenience we encounter.
