This "temporary insanity" plea is going to drive me to insanity! We can do whatever horrible crimes we want to do and get away with it by pleading "temporary insanity". Most of these crimes involve planning and forethought, which do not exist in the mind of the insane. Someone truly insane cannot make constructive plans, and in the case of the Dad Who Microwaves, I can't imagine how on earth you could get away with that when you have to make the decision that it's ok to stick your baby in a microwave oven.
