UPDATE: I just watched a video that makes it clear that camo-clad guardsmen are present in Pittsburgh. You can view that video here.
This photo has appeared at several websites, and it clearly shows the arrested man on the ground and the civilian car in the background. Odd that the camo men look so ‘casual’. Are these guardsmen (no helmut or insignia), or are they perhaps Wackenhut?
WARNING: Strong language — The video below shows men in military camo uniforms ‘arresting’ a G20 protester and forcing the man into a civilian vehicle.
