A psychiatrist has a patient who says he is going to kill his wife. The psychiatrist tells no one, and the patient does attempt to murder his wife. Although his attempt fails, the attack causes her serious injury. She now wants to sue the psychiatrist for not warning her. Assume that no duty to warn a potential victim of a patient has ever been imposed on a doctor. Prepare an argument explaining why you think such a duty should, or should not, be recognized.
