A college professor loses his job because he has been showing films in class in violation of federal copyright law. He retreats to his home, stops seeing friends, and obsesses about his lost job. He stalks former co-workers on the Internet and sends bizarre emails to his former employer's human resources office. He eats poorly and is abusing alcohol. After two months of this behavior, he goes to a freeway overpass and drops bricks through the windshields of cars passing below, killing several drivers. What insanity defense test is best here for the defense?

The Product Test because his actions were solely the result of his isolation.

The Twinkie Defense.

The insanity defense is not available here because the man has not been diagnosed with a mental illness.

The Irresistible Impulse Test because he committed the crimes in public, where everyone could see him on the overpass.
