America Has a Problem With Political Violence—And It's a Growing One

Host Brian Stelter is joined by Barbara F. Walter, an expert on violent extremism and domestic terror, to examine what exactly political violence is and why it’s becoming more common, including factors that may have been at play in the two recent assassination attempts. Walter, a professor at the University of California, San Diego and the author of How Civil Wars Start: And How to Stop Them, tells Stelter there’s a cancer growing in America because a subset of the population doesn’t think democracy serves them anymore.
