In this episode of HATE IN AMERICA, Harris investigates the rise of the lone wolf, revealing startling information about the dramatic increase of this deadly threat. Over the last six years alone, there have been more than 60 incidents of domestic terrorism planned by “lone wolf” attackers or pairs. That averages out to one incident every 34 days. Harris travels the country to investigate three distinct lone wolf attacks, delving into the psychology of the twisted minds of the shooters, including an anti-Semitic attack at the U.S. Holocaust Memorial Museum in 2009, the ambush of two police officers and a bystander by anti-government extremists in Las Vegas in 2014, and the 2015 massacre by a white supremacist at Emanuel AME Church in Charleston, South Carolina.
