A little thought exercise for you, dear reader. Something that I thought of a fair while ago and still wonder about sometimes.

Imagine that you go to sleep tonight, and when you wake up it's September 1st, 2001.

You still have all the knowledge of the last few years. You know that in 10 days the WTC is going to be attacked.

What do you do? How do you prevent it? Who can you tell and (a) be taken seriously, and (b) not be implicated and/or remain anonymous?

Any thoughts?
