2019 Smart Talk Top Stories — research on guns and mass shooters

The 2019 top stories on Smart Talk series continues Friday with conversations that came in the aftermath of the deadly mass shooting in El Paso, Texas and Dayton, Ohio last August.

On Friday‚Äôs program, we hear that mass shooters from the past 50 years all have four traits in common. That’s according to The Violence Project — a think tank that has assembled comprehensive research on mass shootings in America.

Appearing on Friday’s Smart Talk to talk about what the data shows about mass shooters is Dr. Jillian Peterson, PhD, co-founder of The Violence Project and a psychologist and professor of criminology and criminal justice at Hamline University in Minnesota.

Also on the program, there was a renewed call for more gun laws after the shooting in El Paso and Dayton. Advocates both for and against more gun restrictions use statistics to make their case. We talked with Dr. Cassandra Crifasi with the Johns Hopkins Center for Gun Policy and Research about their gun violence findings.-
