Laws of India

Everyone must have come across the news in which 2 cops in Patna were caught on video beating a suspect thief (Aurangzeb), who was later cleared of the wrongdoing. The video's were the epitome of harshness, clearly inhuman behavior on part of the Cops. One man was seen whipping Aurangzeb with a belt. How can this go unpunished, or is it some Indian rule of law that a mob which goes wild should not be punished. More so this gives me the picture I don't wish to see - that the laws of India do not apply to its implementers.
