Did ABC Stage Fake Protester Footage for Newscast?

Video footage appears to show ABC News working with police and protesters to stage a scene to be used as footage portraying the standoff between protesters and police.  While it may appear that way, it does also look like police were coordinating behind the protesters in order to push them out of the right of way they were clearing.

While the footage appears staged, this one is more of the network knowing in advance the police were going to clear the protesters ahead of time and timing their broadcast to match the actions on the ground, according to a source at the scene.
