In Justice (2006)

David Swain is a successful lawyer with political aspirations and he decides to form an organization called the National Justice Project, which sets out to help those who were wrongfully convicted. Charles Conti, a former cop, is the one who investigates all of the cases along with some other volunteers. Once he has enough evidence to prove the person's innocence he gives it to Swain, who in turn gets them out and hogs all the glory.
