On the most recent episode of Gun Talk with Tom Gresham, Massad Ayoob was a guest, and the two talked about Joseph Wilcox, the armed citizen in Las Vegas that gave his life attempting to stop the psycho killers that had burst into the WalMart where he was.
Mas brings up other cases where armed citizens have saved the day, one that I hadn’t heard of before: The University of Texas bell tower shooting in 1966. Mas mentioned that the shooter was pinned down by fire from a competitive rifle shooter, and his national match M14 until police could find the shooter and dispatch him.
Anyways, the interview with Massad Ayoob starts at about the 24 minute mark, go have a listen to it. (Direct .mp3 download)
