Interestingly I recall an Asmov story in which they had the computer that could pretict future murders. It predicted its own demise, therby causing the accused person (actually his son) to try and attack it in order to stop the arrest. Of course, the whole point was that the computer was doing this on purpose because it was tired of dealing with mans problems. I thought of this story while watching MR, even though I know they had nothing to do with each other.
