One-third of nation ill-brained

Actually more than a third of Americans in a Scripps-Howard survey believe the U.S. government was involved in the 9/11 attacks. I was all ready to get upset about this, but:

The level of suspicion of U.S. official involvement in a Sept. 11 conspiracy was only slightly behind the 40 percent who suspect "officials in the federal government were directly responsible for the assassination of President Kennedy" and the 38 percent who believe "the federal government is withholding proof of the existence of intelligent life from other planets."

I'll take my lobotomy now, please.

Update: Geez, didn't I just mention Kennedy assassination nuts? (Answer: huh?)
