Is the federal government doing enough to fight domestic terrorism? This week we talk to one former senior law enforcement official who says no. For nearly two decades, Daryl Johnson was senior domestic terrorism analyst at the Department of Homeland Security and the Bureau of Alcohol, Tobacco and Firearms. Back in 2009 he wrote a DHS Report on “Rightwing Extremism” that was widely circulated in the law enforcement community and was leaked to the press.Instead of taking action, Republicans on Capitol Hill attacked his findings.Johnson explains how and why Donald Trump's election changed the pattern of extreme white nationalists and what can be done about it.
