This is the second video. You can start at about the 20:00 minute mark of the video, that will get you close to the time of the reported incident.
Doesn't really show anything either, the "incident" would have occurred behind the bus in the middle of the middle of the screen, which obviously contradicts the idea that the officer was dragged at any type of speed or distance.
You can see Scheffler in cuffs just after the 25:00 minute mark.
