Just now on Al Jazeera TV, Ronald Noble of Interpol was interviewed. Interpol maintains a database of stolen and lost passports and has millions of them on file. He is concerned because they set up a database with which any government can check the validity of people passing through customs. Only two countries do so. Switzerland checks comprehensively, and they apprehend 100 people every month with stolen or lost passports. France checks passports against the Interpol list only at Charles de Gaulle airport. The question he poses is why are people forbidden to take liquids and gels on airplanes and why are they subject to more extensive searches since 9/11 if the countries involved won't take the time to even check the passports of international travelers. Noble says that "governments will fall" if another serious terrorist attack occurs that could have been averted by detecting people traveling with passports that have been reported lost or stolen. According to him, customs can very cheaply and easily access the Interpol passport database, so why are we not doing so?
