Where in Indian Law does it say that anyone can take the law into their own hands - why weren't the students arrested by the police, at the very least, for assault and battery against the professor. No wonder this land is in such a mess - the police are useless, imbecilic buffoons, good only for taking bribes and 'encounter' killings - the criminal netas in this poverty-stricken land of filth and squalor are happy with this situation.
