So inspection of the UCLA Security policy regarding the use of force reveals that the officers acted within the prescribed policy for using torture techniques against nonviolent / nonthreatening offenders. 

So it looks like the problem at UCLA runs a great deal higher up the food chain than a few rogue officers.  If UCLA is smart, somebody pretty important will lose their job over this and fast! 

Power fears nonviolence for good reason – because acts of oppression against it quickly spiral into these kinds of sticky messes.  Also, because nonviolence works a helluva lot more than armed insurrection against a stronger opponent.  These janitors would have gotten nowhere with physical weapons, but their nonviolent tactics worked in a big way – even after the police tried to trample them with horses.  But if UCLA insists on having violent policies against nonviolent offenders, if they eliminate nonviolence as an option, then they leave few other options than for the aggrieved to resort to violence themselves.  Does UCLA really want a policy on the books to support this kind of spiral?
