Reminds of that one Asimov story about the robot who had a different interpretation of the first law of robotics. If my very hazy memory is right, the idea was that the robot could put a person in danger if it knew that it had the ability to prevent any damage from happening, but once it caused the danger, it could choose not to act and allow the person to come to harm.

I might be remembering this incorrectly, it's been a very long time since I read the story, but that was the first thought that came to mind when reading your comment :).
