[Halo] Why is Dr. Halsey imprisoned for war crimes in Halo 4?

Don't get me wrong, her experiments were ethically heinous and her rationalizations are very dubious. Plus, she's kind of a bitch. 

But it doesn't make sense to me politically for her to have been imprisoned by the UNSC. During the Covenant War Halsey was basically Chief researcher spearheading every research and development program the UNSC had, from medicine to xenotechnology to xenoarchaeology to weapon systems design  to artificial intelligence. She had tons of subordinates below her and allies (but probably not friends, because again, kind of a bitch) among her superiors and colleagues. What happened to all that political clout? I understand that rivals like Ackerman tried to discredit her  to divert funding to their own pet projects, but he's dead now.

 It seems like hypocrisy for UNSC high command to condemn her research as unethical when they were the ones who approved and funded it in the first place. Then they directly built on her work to make the Spartan IIIs (arguably even less ethical than the Spartan IIs) and the Spartan IVs.

Sorry if this seems like a rant, but Halsey's conviction is a bewildering plot hole to me. Dr Mengele lost his war. Halsey *won.*

Halsey really wasn't arrested for her involvement with the Spartan-II program. She was arrested for kidnapping Kelly and for luring Fred, Linda, and Will to Onyx under false pretenses. Now granted, if she was liked by. the heads of ONI most likely she would've just been slapped on the wrist and told to get to work in Shield World-006/Trevelyan. 

Moral of the story is don't piss off ONI.
