Haspel was present at one of the key extraordinary rendition black-sites in Thailand and was involved in the extralegal destruction of the video evidence.
It can't be extralegal if she wasn't prosecuted for it. I think she is just a very tiny cog in a very big machine, a figurehead to throw under the bus if something goes wrong.
She is no more responsible for torture than a janitor who may have also been present.
Torture is illegal. Destroying records on torture with the permission of supervisors is not as there is no international requirement to preserve evidence of war crimes.
