One man is dead, another man's life is at stake, if there's a reasonable doubt in your minds as to the guilt of the accused, uh a reasonable doubt, then you must bring me a verdict of "Not Guilty". If, however, there's no reasonable doubt, then you must, in good conscience, find the accused "Guilty". However you decide, your verdict must be unanimous. In the event that you find the accused "Guilty", the bench will not entertain a recommendation for mercy. The death sentence is mandatory in this case. You're faced with a grave responsibility, thank you, gentlemen.
