I'm reading David Mack's A Time To Heal and I must say I don't like what the Enterprise crew does to General Minza by depriving him of sleep. It's said that Starfleet regulations say that prisoners have to get a certain amount of sleep per day but it doesn't have to be consecutive. This is, at least for humans, clearly torture (http://onlinelibrary.wiley.com/doi/10.1111/j.1749-6632.1962.tb50101.x/abstract), I hope this comes back to bite Picard and company in the ass. Using real world parallels in Trek is totally a huge part of what the show is about but sleep deprivation was excused too lightly. It's just a show, I should really just relax, but I don't like a certain type of torture to be used by guys who are supposed to be enlightened in my fiction. We get enough rubber stamping of torture from propaganda.
