Taxi to the Dark Side--Funding Questions Arise

I’m curious if anyone knows how Taxi to the Dark Side was financed?
The cinematography and interstitials/graphics make it look like a
high-budget government training video. I wondered whose purposes it was serving?

Responses included:

When was the last time anyone saw a “high budget government training video”?

and

…a training video on torture, especially if it
featured some of the people interviewed in the film, would make a
provocative companion piece.
