Post #10 was just a post of an article, which talked about the ricin mailing in December, which was attributed to a disgruntled trucker.
It may have been pulled, because the article was from the WP and the poster copied the whole thing. ( I am not sure, I just read it, replied, and poof! it was gone, so that's what I surmise, because otherwise there was nothing wrong with the article).
"The letter was addressed to the Department of Transportation, and the sender was protesting the new hours-of-services rules for truck drivers. The typewritten letter was from someone who claimed to be a fleet owner of a tanker company. It demanded that present laws regarding HOS remain unchanged."
