IN THE FEDEX: At my door this very minute, a copy of Debunking 9/11 Myths: Why Conspiracy Theories Can’t Stand Up to the Facts, by David Dunbar and Brad Reagan. It’s a much-expanded version of the Popular Mechanics mythbusting article from last year, with a foreword by John McCain on the toxic nature of the circulating conspiracy theories. Perhaps they should teach it at the University of Wisconsin.

The Amazon comments, however, suggest that the conspiracists are alive and well.
