Many people, including many of ourselves, have experienced sleepwalking or have known someone who has sleptwalk. Although it is not like shown in the movies where a person in a zombie-like trance is walking around, it can still be very dangerous. 
People have been known to drive cars, turn on electronics, and well as make love to people when they are sleepwalking. But in the course of history, someone possibly committed murder while sleepwalking. The real question is, can this be justified and used as a valid arguement for legal defense. It almost seems too hard to falsify, and absolutely unethical enough to test. It seems like having a trial with defense like this could really complicate things where the court-room could end up at a standoff and obstacle. I wonder if this will ever pop up again in court, and if it does, i am very interested to see how it turns out.
