Video shows police officer telling second student to leave or "you're gonna get tased too"

I just watched the video again, and at the very end, about 6 minutes and 40 seconds into the video, a short-haired white cop with brown hair tells a student in a white t-shirt, who appears to be doing nothing at all, to get "back" somewhere "or you're gonna get tased too."

It's clear as day on the tape. There is no question whatsoever. You can watch the video in the post below - click and give it a second to download completely, then scroll ahead to around 6 minutes 30 seconds and listen closely when it gets to 6:40.
