At the risk of Godwin-ising the discussion on the first page (*)
Police can say 'It's not my decision, the computer told me to do it,'
I believe the actual phrasing you are looking for is "I was only obeying orders." and not only has this one been (quite famously, IMHO) shot down in court, it is plain embarrassing when the orders you are following have come from a machine rather than a superior officer.
(* In fairness, it's a fairly high risk when the topic is "being a racist bastard and trying to pin the responsibility on someone else".)
