Friday saw more protests over the police murder of Antwon Rose in East Pittsburgh. The evening’s action started conventionally enough, meeting at the Wood Street subway station downtown at 5:30, and stepping off around 6. At least 200 people took the streets, marching slowly through downtown and stopping frequently to block intersections while holding speakouts. A trailing caravan of cops accompanied the march, but they weren’t doing anything yet. More cops on motorcycles circled, blocking off intersections as marchers approached, and causing even further disruption to rush hour traffic.
