Beware Of Pickpockets(1981)

Big Nose Pao is a faithful and honest constable that has been tasked to arrest Three Hands, a pickpocket. However, each time the pickpocket is caught, he's released by the lack of evidence. Although Three Hands steals for a living, the money that he takes from the rich people, is spent on the seven poor orphans with whom he lives in an old shaky church.
