Thanks for pointing out this latest piece of nonsense.

As Daemon says, all the terrorists have to do is get better at disguising their intentions, become sleepers, build an honest life for themselves, obey the law, get all the ID in the proper way, then walk onto a plane and blow themselves up. It's not exactly rocket science.

In fact, I think the incompetent Glasgow fire-bombers held responsible, respectable positions in local society - presumably they would have qualified for all the proper ID.

And I would also have thought that, if pushed into a corner by measures like this, terrorists would begin to use innocent people as bombers, kidnapping families and holding them hostage, like the more unpleasant bank robbers do now.
