In video after video recorded by protesters and observers in Minneapolis, you can see that the agents are also filming the observers, in a sort of mutual surveillance state, I wrote last month (and one that my colleague Tressie McMillan Cottom covered this week). But in truth, it isn’t really mutual. The Department of Homeland Security has tried to criminalize journalism by characterizing reporting as doxxing and observing as impeding law enforcement, and its agents are now threatening and sometimes assaulting people who record them — an effort to secure, in addition to the state’s monopoly on violence, a monopoly on surveillance. This may be another reason so many immigration officers are masked while on duty: They know better than we do what it means to show one’s face. In Minneapolis and elsewhere, agents now carry tools of surveillance into the field, just as they do their guns.
