Go watch the video again. Tan shorts guy did throw down his hat, did not approach to the front of the officer, but came around to his right side and kept coming until Casebolt drew. Tan shorts guy did run off and around to the right with LEO after him.

Watch seconds 28-38.
In a nutshell then:
Unlawful acts by the Casebolt?
None
Unlawful acts by the various members of the crowd?
Refusal to comply with lawful police orders, by the whole non-compliant mob.
Resisting, by Dajerria Bectom
Simple assault, by Bectoms friend who encroached on Casebolt subduing Bectom
Aggravated assault, by each of the males who rushed at the officer while he was subduing Bectom

Oh, and I believe tan shorts guy is White.
Like I said, you can go all grassy knoll on this and create whatever you want to create in your mind, but the lousy cop resigned.
He was way overboard, obviously, and his resignation and his short time with the Highway Patrol, probably reveal that what we saw, is why he resigned.
He just isn’t suited for this work.
