I keep thinking about how, in 2016, it took me just one day to infiltrate multiple militias via Facebook. Then I drove to one group's temporary military base in the desert, the coordinates of which were posted on Facebook. These people plan everything in the open.
They do that because they are so confident that they won't get into any trouble. In the five days I was undercover on their "base," I saw cops and border patrol praise them. They've been show since well before Trump that they have nothing to worry about.
After I published my article, the Department of Homeland Security reached out to me and asked if I had any advice about how to infiltrate such groups. (I told them I didn't.) Pretty unbelievable given that all it took was spending a few hours online.
