*Intermittently through the month of September, we are airing newly recorded as well as archival interviews to commemorate the 25th anniversary of 9/11*. Part One- Dave Dunbar, co-author of "Debunking 9/11 Myths: Why Conspiracy Theories Can't Stand Up to the Facts." The book, which actually grew out of an article in Popular Mechanics, methodically examines the many conspiracy theories that sprang up in the wake of 9/11. Part Two- A 2005 conversation with the late Dr. Jack Keating, who was chancellor of the University of Wisconsin-Parkside from 1998 to 2008. His academic field was Psychology, and the primary focus of his research was on how people behave during disasters and other kinds of crisis- and what sort of trauma do they experience and carry with them in the aftermath.
