For the third consecutive day, protests against police violence (and less so the deadly retaliation by Micah Johnson) continued on Saturday night across America and shut down key roadways and transportation arteries in a number of U.S. cities on Saturday, resulting in mass arrests. The protests stretched into early Sunday morning in Baton Rouge and St. Paul, where tensions are most raw after the deaths of Alton Sterling in the Louisiana city and of Philando Castile in a St. Paul suburb.
