What happens if someone from the past shows up in the enlightened society of the Federation and we know tha he commited crimes by "todays" standards? What would happen to a temporaly displaced Djingis Khan. I will let Flint go because him butchering people as Alexander was such a long time ago. But what happens if in the characters life the crimes were fairly recent? Would that temporarily displaced person stand trial? Is there a special DTI jury and judge for these people? I think an episode about this moral question would had made great Trek episode. What do you guys think?
