Nothing but death for Santosh
Under public pressure and with active media support the judiciary is back on rails. If we have to value human life the best example that can be set would be by bringing to book not just Santosh Kumar Singh but also his father.
Sons of eminent and rich people would learn a lesson not to think that they can get away with any crime in the false hope that their fathers or grandfathers or godfathers can come to their rescue. This is what Gandhigiri or Ramayana teaches us. India can set an example for the whole world to emulate.
