I think (most of or all) those countries also have a written constitution (which we do not), enshrining their civil rights and protecting the population against many abuses.
Try and imagine what it would be like here if, say, you looked a bit like an immigrant, (you know, a bit suspiciously brown or wearing a shalwar kameez or a burquah) you'd be having to step aside and produce your card multiple times a day.
Bear in mind that the 7/11 London bombers were all legal citizens, the 9/11 hijackers all had the correct paperwork ... having the right ID wouldn't have made the slightest difference to the crimes.
