I examined this blurry protrusion above the ridge line and I believe you are correct. This is Crooks’ head looking over the ridge cap but there is no rifle. He is not taking aim. He’s probably wondering what’s going on.
In the first photo, we see that Crooks’ body was found in the third channel from the edge of the connector hallway between the two buildings. The blood trail is visible.
The second view is Google Earth with a red line indicating the third channel projects to just to the left of that window.
The third view is your screenshot showing that position lines up perfectly with what is Crooks’ head.
The next screenshot is the police headcam video showing the ridge cap and that there is no way a rifle barrel could have been poked under it.
Crooks does not have his rifle aiming above the ridge cap at the time of the first three shots.
The last screenshot is at about the 13 second mark of your video. I lined up the edge of the window with what is quite blurry but does seem to be Crooks’ head still above the ridge line, no rifle is visible.
THEREFORE the obvious conclusion is that Crooks did not take those first three shots.
