... and I ask again: "... and how do you suggest this will help against hitherto unknown suicidal terrorists?" In other words, after the suicide bomber -- who was previously unknown to be a terrorist -- attacks and dies himself/herself, how does the US VISIT program or such other things help?
Even if a system like this was in place prior to 9/11, the overwhelming majority of the 9/11 attackers would still have been in place in the United States.
