Rules of Engagement

While the Defiant escorts a convoy of Cardassian medical ships, Klingon vessels attack. Worf, in command, fires on a ship that decloaks in front of him, only to learn that it was a civilian transport carrying hundreds of passengers. The Klingon Empire demands that Worf be extradited for trial, and a Vulcan admiral, T'Lara, presides over a hearing on the station. Sisko defends Worf against Ch'Pok, a shrewd Klingon advocate who argues that Worf is driven by bloodlust and a desire for revenge. Testimony from Dax, Quark and O'Brien does little to help, and Ch'Pok goads Worf into attacking him in the courtroom. Then Sisko's investigation reveals that the passengers listed as dead had all been killed months earlier in a separate crash: the whole incident was staged to frame Worf and embarrass the Federation. Worf is cleared, but Sisko reprimands him for firing without identifying his target.
