I forgot to add... someone asked if the Mutara sector was inside Federation space.
I don't think it was ever explicitly stated, but it's VERY strongly indicated that it was.
This would mean that Starfleet might not have felt the need to send a more heavily armed ship to Genesis. Or another as a guard for the Grissom. (Which, honestly, given it seemed to be in somewhat close proximity to Klingon space, was stupid, politics or not.)
That Klingon lawyer calling for Kirk's head in TVH made me laugh , particularly after Sarek (correctly) made several points about what Kruge did before Kirk even showed up.
Your guy trespassed into Federation space, destroyed a Federation science vessel, killed Federation citizens, stole top secret Federation information (Genesis project)... but Kirk was the bad guy here because he stopped Kruge and took his ship? I'll give him points for being ballsy enough to even entertain that idea in front of others, but damn did that make them look stupid.
