The tl;dr seems to be an underage black person tried to buy wine, apparently stole wine, then there was a fight with the owner's son. There was a demonstration that was probably based on an unclear understanding of the events. So people over-reacted to events, yes they were stupid to do. But you shouldn't use this as an excuse to clutch one's pearls and conclude colleges have lost their way. This looks like a cya activity after the true(-er?) facts came out.
