The other general comment I have about the report is about its scope: it was designed to protect the Administration and its method of legalizing torture. For example, the report notes:
We did not examine issues related to DOJ Office of Legal Counsel opinions concerning the legality of several interrogation techniques the CIA sought to use on certain high value detainees. While senior FBI and DOJ officials were aware of these opinions, an assessment of the validity of the OLC legal opinions was beyond the scope of this review.
Similarly, the IG report apparently did not review what happened to complaints about torture once they got to Bush’s top aides (though the report doesn’t actually say whether this was because of a scope issue or because Bush’s aides refused to cooperate).
