I remember who did it -- and after ten years of studying and trying to understand, I know why. If you really want to honor the brave and the innocent dead, educate yourself. Read the Koran. Then look up "Abrogation". There is a lot more to know but that will give you a start.
All this self-indulgent wallowing around in "tribute" -- maybe it would be better to quietly put a plaque somewhere at the Pentagon, at the WTC site, and in Shanksville. All this other hoopla is a bit too show-biz for my taste. We are not that weak, that teary, that old-womanish. If this were a movie, somebody would slap us silly and order us to get a grip.
We are Americans, strong and brave. That is what we should never forget.

Having said all that, and in a nod to inconsistency: Here's the Budweiser 9/11 tribute -- shown once. I remember I saw it and tried to describe it to George and could not stop crying. Still affects me like that.
