Witness to An Incident

Cagney & Lacey

One of the uniforms accidentally kills a civilian, mistaking him for a perp. C&L both see it, but they have very different recollections of the event. Marquette and Samuels pressure Lacey to agree with Cagney, but you know how stubborn she is. The bad guy is a crewman on a foreign ship, and it ends with a chase on the ship.
