This is one of the worst episodes of Deep Space 9. The writers portray the Cardassian courts as completely ridiculous. A true dictatorship show-trial is a clever and sophisticated affair- It's designed to fool people. The court portrayed here is a bumbling nonsense that makes the Cardassians look like weak fools (which they are not).
I have absolutely NO idea what kind of idiot it takes to write an episode as childish and badly written as this one. The whole thing makes no sense at all. And I can't be bothered elaborating on it, as it's already wasted enough of my time.
The writer of this episode clearly didn't do ANY research into real show-trails or the politics of real dictatorships.
I also note by the rating my review has so far received that the crazy Star Trek fanboys are on the case.
