3x13 - The White Shadow

An elderly woman is mugged on the street at night by two big, tall black men, and the description she gives the police matches both Coolidge and Franklin, who happen to be out on the town that night. The police apprehend the two with Thorpe looking on. Thorpe observes what appears to be police brutality, reaches into his pocket to get a pen to write the cops' car number, and is shot by one of them.
