Director Michael Dorn cuts a quick pace to build the tension in this Bashir episode that initially seems like a redo of TNG's "The Drumhead" - a witch hunt filled with paranoid hearings that mines past episodes in search of evidence of wrongdoing - before becoming more like "Future Imperfect". (Specifically,"Inquisition" gets a lot of mileage out of "Dr. Bashir, I Presume?", "In Purgatory's Shadow", and "Statistical Probabilities"). Alexander Siddig, avoiding the temptation of overacting, plays it well, showing frustration but never allowing Bashir to lose his head. He's joined by guest star William Sadler, serving as the episode's Joseph McCarthy, who gives a memorable performance as Sloan, injecting the mysterious figure with an almost cheerful feistiness as he tries to corner his opponent with words. Meanwhile, just as Picard is pulled into the fray in "The Drumhead", a frustrated Sisko comes to the aid of Bashir, allowing Brooks to deliver some passionate arguments, which is right up his alley. But as events and characterizations get more and more preposterous, it becomes evident that all is not as it seems, with Sloan turning out to be more Nathan R. Jessup than McCarthy, all but saying, "Son, we live in a world that has walls, and my existence, while grotesque and incomprehensible to you, saves lives!"
In the end we're teased with the promise of a sequel, which happens in six season's "Inter Arma Enim Silent Leges". Meanwhile, the mysterious Section 31, introduced here, becomes a somewhat recurring part of Star Trek from here on out.
