Ward was the other of two detectives investigating the murders of the Civil Rights activists (1964) in the movie
He was played by Williem Dafoe.
Ward doesn't start off like this. Ward starts of as a man of the law who wants to be hard on the criminals. Though he's kinda a jerk in the movie toward his workers, he's not bad in and off themselves. It's what he does in the end, when he participates in his partner's plan to turn Lester against his pals. Rupert plans to pretend to be the KKK, firebombs the house of Lester, chases Lester and one of his agents pretends to lynch Lester, until Rupert and Ward come in and "save" him. To me, Ward is a hero turned to the dark side.
