Talk on the CPRC's new research on Mass Public Shootings and Gun-free zones

Dr. John Lott gave a talk on the Crime Prevention Research Center's research on Mass Public Shootings and Gun-free zones.  The video is available here.  Unfortunately, the first few minutes of the beginning of the talk is missing. The first reference is to a quote from former President Obama that if guns stop mass public shootings, the US shouldn't have any mass shootings. Beyond Lott's response to that point in the video, a list of mass public shootings that were stopped by concealed handgun permit holders.  The slides in the talk are based on information in his book "The War on Guns."
