Thank you for providing your well thought out breakdown. I think you may be onto something. I just found another cell phone video in which the people in the video are fleeing out of the gate 7 area toward and through the parking lot of the Oasis Apartments. The shooter is not over there. The sounds in the video do not sound close enough for the shooter to be there. If the shooter were those people in the video would have been quick targets below.
