New Zealand Massacre: The Rise of White Supremacist Ideology

The threat from violent white supremacists is on the rise worldwide. The techniques used to spread the ideology are comparable to those used by Islamist extremists. Host Carol Castiel talks with Kathleen Belew, author of "Bring the War Home: The White Power Movement and Paramilitary America,” and Ali Soufan, former supervisory FBI agent and the CEO of the Soufan Group, about the scope of the threat in the wake of the recent massacre at two New Zealand mosques, and what must be done to combat it.
