Yeah, but that's part of why the ending bothers me, and is very flawed in my opinion. Khan doesn't even get tried for his current crimes if you're taking a strict interpretation of the final scenes, let alone serve out some kind of appropriate sentence. He gets put back into the freezer along with his crew. It's a very 'got off scott-free ending' unless someone posits that it's all happening concurrently and that in the year between the memorial service and the events of the film, the trial did happen and a Federation judge or jury decided the most appropriate sentence was... to be put back into a bottle in case of sequel.

That seems highly unlikely to me. Even if the Federation is the most enlightened place in the universe, surely 'let's freeze him again so he can do it again' isn't a decision a wise, informed and grieving populace would take.

I think a better ending might have been a shot of Kirk replicating the mistake of the past and abandoning Khan (by himself, maybe) on some planet. Or maybe we should get a quick shot of Khan on trial or languishing in a Fed prison. That way, the Federation civilians get their justice with honor, and Khan is still alive for future films.

As it is, it really, really sticks in my craw, because at least when the last movie blew up Vulcan it was treated with the serious reaction it deserved. Spock never reduces it to just the death of his mother except when appropriate. Here, you'd be forgiven if thinking the memorial was strictly for Pike.

(I know a few radical leftists who are Truthers too, it's just much less common in the states than the vast paranoia of the right.)
