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.
