A true Trek story. A great vehicle for Deanna. Inspired casting of Riva. I can't help but feel that Geordi could have been much better utilised in this one.
Riker; "It's not our job to police the galaxy" - This was obviously meant as a political statement, one that refered to the foreign policy of the U.S. at the time the episode was written. But it's a false statement, there are many times when the Enterpise has been called to "police" something. In this instance, whether they like it or not, they are involved merely by transporting the mediator. Why did Picard and company not know that the mediator was deaf? He "negotiated several treaties between the Klingons and the Federation". Does Starfleet not brief their Captains before sending them on an errand?
Stinger: Picard grabbing hold of the deaf mans ears and SHOUTING.AT.HIM.SLOWLY to be understood.
