In most "school yard fights" the combatants know each other. If there's evidence to charge them with assault it was clearly not on the basis of knowing this man, and therefore likely that it was a racially-based attack. There were certainly enough witnesses who could have been charged as accessories, then allowed to plead down for testimony.  This is not in the best interests of the people of Port Angeles, who will have one more incident coloring them as racist as a result.
