CSI: Crime Scene Investigation Episode 10.04 Coup de Grace

The racially charged story of a cop that kills another cop by accident and the infighting between the police and the local community that ensues as they work out the ugly details of the case. A veteran cop, who is advancing towards retirement shoots and kills a black man in a fast food joint. It appears as if the final shot was point blank, and after the man was already down on the ground. Catherine and Brass are called in to investigate. Catherine is the lead CSI in the case, and all the local police give her attitude for being defacto IA. She is unbiased until the facts reveal that the cop actually shot another off duty cop, and actually knew him. The CSIs figure out that the final shot or "Coup de Grace" came from another gun. It seems as if the veteran cop is cleared of murder, but asked to take a leave of absence. Langston sees the cop as he gets into his car at the end of the episode and blows his brains out. The shame was too much for him. In his autopsy they discover that he was actually legally blind, but too proud to tell anyone. It was an accident after all.
