As noted yesterday, the most surprising twist from the Saturday night protests that swept America, the third consecutive night of demonstrations against police violence, was the arrest of DeRay McKesson, one of the leaders of the Black Lives Matter protest movement, who was arrested in Baton Rouge, where he traveled earlier Saturday “to demonstrate in solidarity with residents angered by the recent death of Alton Sterling after an officer-involved shooting that was captured on video.” McKesson was taken into custody around 11 p.m.
