It's probably just as confusing at the other end. You can bet there's more than a few bad guys slipping out under the radar.

Not nearly as many as are slipping by on car or by foot with no screening whatsoever. The problem is who gets a French/US/UK passport; the time to address it is not when the s--- hits the fan, and the way to address it is not to have junior officials screening people by how difficult it is to spell their surnames.
