The strange and frightening images of unidentified military-looking men taking protesters off the streets of Portland, Oregon, and into unmarked vans may be headed to a city near you if that city is, as President Donald Trump declared Monday, run by "liberal Democrats." The teams of masked authorities seen in Portland dressed up for war like special forces apparently belong to the Department of Homeland Security's Customs and Border Protection Unit. They're trained for drug missions, but ... they've been dispatched to American streets. Trump suggested more federal agents will soon be headed to more American cities. The fact that DHS would deploy its own warriors into American streets without much discussion and without a clear mandate (they're vaguely supposed to be protecting federal buildings?) is dark-of-night dystopian stuff. Meanwhile, the militarized response has led to more violent levels of protest in Portland, where racial justice and anti-police brutality demonstrations have lasted more than 50 days. The atmosphere has not been helped by the efforts of federal agents, according to Portland Mayor Ted Wheeler, who called the administration's actions "abhorrent." "People are being literally scooped off the street into unmarked vans, rental cars," Wheeler [said]. Both Wheeler and Oregon's governor have demanded the federal authorities leave. And multiple House committee chairs are also calling for an immediate watchdog investigation.
