LISA PINA-WARREN, the executive director of The Nonviolence Institute, joins me for a compelling conversation on how they square the use of nonviolence to mitigate the rise of gun and gang violence in Providence. It is a compelling conversation that includes her personal story. Lisa lost her brother and family members to gun violence.  It is so tragic that we experienced another school shooting, this week in Georgia. Guns are the leading killer of children in the U.S.  We have more mass shootings than any other country on the planet. So much more work needs to be done to prevent unnecessary deaths from gun violence.
