I too have been listening about such adverse cases which seems to be very painful, and even sometimes it's too bad for the innocent because the police seems to have power so it uses any sorts of mode but that's absolutely bad. The first time I heard about such case was that the police had a doubt about a criminal which it wasn't aware of so they saw a man running along the train on railways and called him once twice, the man he was just missing his train didn't heard about it and kept on running and at one fine point the police shoot him and killed him, but he was found innocent. That's too bad to hear
