7/10. Important docu on worldwide, covert killings by JSOC, the only military unit that reports directly to the US President. Scahill samples cases of murdered innocents. Probs: The docu is weak on backgrounds, and rather too author-centered. However, valuable education. As one interviewee says, a big hammer was created, and it will keep looking for a nail. // Original string music, played by Kronos Quartet!
