This episode was considered by writer Ira Steven Behr to be the first in a series of episodes designed to take a darker look at the utopian Federation that Gene Roddenberry had created.
Nitpick: Dukat claims that the Zeppolite freighter can reach a top speed of warp 9.8. This is an astonishingly high speed for a civilian freighter, given that state of the art Starfleet ships of the era (Enterprise-D, Voyager) have similar top speeds.
Ferengi Rule Of Acquisition #3: Never spend more for an acquisition than you have to.
Dukat's statement of "On Cardassia, the verdict is always known before the trial begins" was our first indication of the Cardassian legal custom of "guilty even if proven innocent" and became the inspiration behind the episode "Tribunal".
Goof: In Sisko's office, Kira's Bajoran comunicator is upside down.
Quark: Vulcans are a species that appreciates good ears.
Dukat: Anyone can blow up a ship. Hah! But to look your enemy in the eye, knowing that you will remember his face for the rest of your life... that takes a stomach much stronger than you'll ever have.
Amaros: We'll see about that.
Sakonna: No. He's right. We do not possess the Cardassians' gift for inflicting pain. Nor would we want such a gift.
Kira: (talking about Dukat) Why risk our lives over someone who has caused so many deaths? The way I see it, he's geting exactly what he deserves.
Sisko: The Central Command wants him dead. That's reason enough for us to want him alive.
Quark: Sakonna was in the market for certain items which I was able to obtain for her. At a considerable discount, I might add.
Sisko: What items?
Odo: We're waiting.
Quark: Let's see, where to begin? She wanted some deflector shields... navigational arrays... maybe... a couple of hundred photon torpedoes...
Sisko: You know what the trouble is?
Sisko: The trouble is Earth.
Sisko: On Earth there's no poverty, no crime, no war. You look out the window of Starfleet headquarters and you see... paradise. Well, it's easy to be a saint in paradise. But the Maquis don't live in paradise. Out there, in the Demilitarized Zone, all the problems haven't been solved yet. Out there, there are no saints... just people. Angry, scared, determined people who are going to do whatever it takes to survive. Whether it meets with Federation's approval or not.
Dukat: How barbaric. On Cardassia, the verdict is always known before the trial, and it's always the same - guilty.
Sisko: Then why bother with the trial?
Dukat: Because the people demand it. They enjoy watching justice triumph over evil every time. They find it... reassuring.
Sisko: What if you try an innocent man by mistake?
Dukat: Cardassians don't make mistakes.
There's a button labeled "947" between the two monitors in Cal Hudson's ship.
Writer Joe Menosky began including references to the number 47 in almost every episode of Star Trek since season four of The Next Generation. It is an in-joke, referring to The 47 Society at Pomona College in California, a college which Menosky attended.
Cirroc Lofton (Jake Sisko) does not appear in this episode.
