B R Chopra always made movies which had a social message and most of the times was miles ahead of his contempraries. He made Kanoon in the black and white era. It was the first hindi movie without a song. It showed the concept that an upright Rajendra Kumar, an honest lawyer believed in "That a thousand criminals may go unpunished, but an innocent man should never be punished". It also showed his opposition to the death penalty because if an innocent is given death punishment, then you cant bring him back. That God has given us life and we humans have no right to take it from someone. When the history of Bollywood is written Kaanoon will always find a prominent place in its annals as a landmark and path breaking movie.
