I'm not sure exactly what I see in those videos, but I can certainly believe from the content of the NEN call that GZ wasn't parked at the clubhouse when the call connected. I don't know if he pulled over and dialed a few times, or got a busy signal, or maybe waited to see TM come and pass by before deciding to call. I'm not sure what to make of the light movement captured after he leaves the kiosk. IF we can assume his was the only vehicle on TTL at this time, then it sure looks like he did a u-turn. I'm not sure why he'd do a u-turn if he had a visual of TM out in front of him. I guess its possible he stopped at the mail kiosk because he saw TM, got a good visual then decided to move on down TTL and turn around to observe him. That doesn't seem to fit Dee Dee's narrative of GZ trailing behind TM in his car as he left the mail kiosk or the description GZ gave during the walk thru.
