That would be Christopher Lee Polis, age 22, Will be 23 on april 28th.
I’ve followed/read about this incident the last few days (kudos to you for posting all the info before it was common knowledge).
No excuse for the assault I watched on the video. You don’t kick/punch/fight a person who is already down and not fighting back. He/she was down. Fights like this used to break out 25/30 yrs ago, when I was a kid, so this isn’t anything new. But you don’t keep fighting a person who is already down.
