Peter Diaz is the leader of 'American Wolf'. He’s also the proud owner of numerous automatic weapons. He and his comrades regularly train at a shooting range. They take their guns to anti-racism protests. Diaz says: "These people are not protesters. [They’re] criminals, actively working to destabilize our government, destroy our way of life.” For three months, the militiamen have patrolled the streets every day. But now their opponents on the left of the political spectrum are forming similar groups, like the "New Black Liberation Militia" in Atlanta. In their words, their mission is to ensure Black survival in the 21st century. Is it just a matter of time before right- and left-wing militias come into direct conflict? A report by Oliver Sallet.
