In "Bread and Circuses" Kirk beams down to potentially hostile territory with Spock and McCoy. That's the captain and first officer separated from the ship with no security squad. They are quickly captured and disarmed. Luckily, their captors are nice and let them go. Then they are promptly captured and disarmed again by police-state forces who are not so understanding. Now the captain and first officer are locked up down on the planet with no way to contact the ship. It's a realistic scenario to say that they might never be found and freed, no matter how many men Scotty beams down to search for them. Cities are big. Do you search house to house? If you figure out that they are in jail, the authorities might decline to hand them over. Do you use phasers to conquer the government? Kirk gets out of this jam by certain strokes of luck, including Merrick handing over a communicator at the crucial moment. Who's to say that was going to happen? And without it, he's still stuck and about to be hunted down by 200 cops. I think if this were a true story, Kirk would be in trouble with Star Fleet despite getting away from his captors. Is it too much to imagine that he would be relieved of command for such recklessness? What should he have done differently, starting from before he ever beamed down?
