Read the PDF of the letter sent to Dan Levin, then acting head of the Justice Department’s Office of Legal Counsel in 2004. While some items are redacted to spare your delicate sensibilities, I think you’ll get the gist of what to do pretty quickly. Just remember like in the song — you have to be cruel to be kind!

The fax cover sheet has a brief note, “Dan, a generic description of the process.” The name of the sender, based at the CIA, has been obliterated. [...] The document provides a step-by-step manual for extraordinary renditions.
[...]
None of this information is surprising. In fact it all tallies perfectly with the description of the renditions program that can be derived from the report prepared by the International Committee of the Red Cross, which used the appropriate legal designation for these techniques: “torture.”

But this is an historical document, right? President Barack Obama shut down the black sites and the extraordinary renditions program immediately after taking office, right? Well, not entirely.
