Here's a link to what Donuel is talking about:

http://www.cbsnews.com/news/sources-us-intel-warning-of-possible-al-qaeda-attacks-in-us-monday/

It looks like a real CBS (Columbia Broadcasting) page, but it sure is devoid of convincing detail. Not one intelligence agency source is named. Maybe CBS stands for Creative BS in this context.

Q.If you were a normal, decent person who somehow learned of a terrorist plot, what would you do?

A. You would quietly inform authorities, hoping they would prevent the attack. You would also hope to remain anonymous, fearing reprisal from terrorists.

You certainly wouldn't go to journalists, who are noted for their squirreliness. Not to mention that journalists don't prevent crime, they merely report crime.

I certainly hope that these rumors don't give some suggestible nutcase the idea that he ought to attack somebody.
