Why? Hmm have you ever heard in any political parties poll platform anywhere in India two things: a) Reform of the police system and making them professional and independent b) Reform the Judicial system to make it fast, efficient, hire more judges and make them independent? Ever? No?
Why? Because it is in any political parties interest to grab on to power and Police is its muscleman and executioners and slow and corrupt Judiciary is necessary to ensure they will never be punished and in fact use it to further their agenda. This is controlling the sheep 101.
Mandir Masjid Bulldozer? Yes!. The Police/Politician/Judiciary is the Shit Sandwich Indians eat everyday.
