The events of today, 2001 September 11, are still unfolding. Those who know something aren't talking, and the contrapositive.
It's much easier to destroy than to build, to kill than to create. The fanatics who planned the deaths of so many people aren't cowards. They are criminals, tragic in their confusion. It will take time to find them and bring them to justice. Patience.
As a US Government building was being evacuated this morning, a person walking ahead of me spoke to a uniformed security officer: "Thank you for being here."
Yes --- thank you to everyone, in all the nations of the world, who protect and serve, who help to keep the peace.
