What he did was wrong, but the punishment is not right. We know how the saying goes. The appropriate punishment would have been to force him to clean the chalk off. That's also the appropriate punishment for any vandalism. A written apology and reparations for the vandalized property. What I don't agree with is the idea that using chalk makes it "not vandalism" -- it still is vandalism. The punishment is absurd, though. Obviously BOA has heavy influence over the authorities in this case.
