David Lane

David Lane has spent most of his career as a key background organizer for the evangelical community. In recent years, he has worked behind the scenes to connect pastors and other religious right activists with conservative politicians. His work has been bankrolled by the rabidly anti-gay and anti-Muslim American Family Association, which the Southern Poverty Law Center lists as a hate group.

Craig Cobb is best known for his botched effort to transform the tiny hamlet of Leith, N.D., into an Aryan stronghold, a secret campaign which ultimately landed him in jail and, in 2014, on four years of probation while tethered to a monitoring device. An itinerant neo-Nazi who joined a whole variety of racist groups over the decades and even operated from Estonia for a time, Cobb became known as an especially vicious character who posted horrific videos of things like Russian neo-Nazis beheading immigrants on his Podblanc video-sharing site.


Harry Cooper is the founder of Sharkhunters International, a company that organizes tours to sites that were historically important to the Third Reich, such as the Wolf’s Lair, Hermann Goering’s house, and Hitler’s vacation homes in Bavaria. These tours, or “patrols” as they are referred to, are presented as opportunities to “relive history” — in this case, the troublesome history of the Nazi leadership of the Third Reich.
