I'm intrigued by the report that an older man tried to get the bomber onto the plane at Amsterdam without a passport. There is no way you can travel to the States without a passport - for starters it contains your US visa. Airlines are fined thousands of dollars if they inadvertantly allow someone to travel without a passort - it just doesn't happen any more. Also, this would simply draw attention to the bomber which obviously he could do without. No doubt there is a lot of conjecture and simply wrong information doing the rounds at present. Once a full investigation has been completed, hopefully a more complete and accurate account of this bomber's journey details will emerge. Security is only as strong as it's weakest link, and unfortunately human error seems to have crept in here, both in not dealing with the intelligence and in not completing physical checks thoroughly. I see that Obama has just publicly roasted his security services - quite right given the resources at their disposal.
