Yes, it was a show trial, and standards of justice undoubtedly vary by culture, such as the Cardassian standard of "guilty until proven innocent."
But Kirk and McCoy's trial barely made any attempt to even look credible!
The trial ends thusly:
Chang: "Captain Kirk, are you aware that under Federation law, the Captain of a Starship is considered responsible for the actions of his men?"
Kirk: "I am."
Chang: "So if it should prove members of your crew did in fact carry out such an assassination?"
...
Kirk: "As Captain I am responsible for the conduct of the crew under my command."
Chang: "Your honors, the State rests."
The state rests on what?
They established Kirk would have command responsibility in such a hypothetical scenario... but they never actually 'proved that members of his crew did in fact carry out such an assassination'! The evidence was "entirely circumstantial" as Colonel Worf said. But judgment was passed anyway.
And so the Klingon legal system looks like a complete joke on the galactic geopolitical scene.
Please discuss.
