The beating looks bad (oh, hell, it is bad), but will be defending by some. Hell, it isn't easy being told to restore order in riot. But lying on your report? Now that gets you fired.
But regardless of the specifics, what are you supposed to do with thousands of stupid drunk stupid college students "celebrating" (AKA: good-spirited rioting).
This is just one reason why my father hated jocks and scholastic sports.
How come when society has a problem, somehow it's the cops who always end up taking the fall?
