I’m not going down any more rabbit holes. I’ve already come to my conclusion that Crooks is the “ONLY” shooter with assistance before (planning) and during (rooftop access) the rally. He’s the patsy and blew the shot.
However, they could not have found a better venue than the AGR building to try and pull this off. It’s so close to the rally and there are more nooks, crannies, doors, windows, passages between buildings, and rooftops, you can shoot from one area and within minutes be in a completely different building and point on the compass.
@macd brought this to my attention. The first picture is the location where Crooks is suspected of climbing onto the roof. Note the door across from his suspected access point.
In one door and out the other never to be seen. I believe the rooftop footage of him getting into position discredits this line of travel, but an example of how easy it would be to maneuver around and through the AGR building in plain sight if you were granted access or had the proper credentials.
