I think that we need to be balanced here, and also acknowledge that KA, his parents, and supporters see KA as the victim in this encounter. He was in the tent of the opposing team, we don't know the rest of the story, was he invited? There to get out of the rain?
As far as we know, KA was confronted by AM, and the skirmish escalated quickly. Did KA feel threatened? Did KA feel like he could be at this area?
This will go to a grand jury, there appears to be plenty of witnesses, and video footage.
Let's wait and see. We may not agree with the actions of KA and his family, or even understand them. But, KA's family is supporting their son. That is commendable. They have KA's story. And see this from his point of view.
