23. Shakespeare, a playwright, is walking down the street. As he passes a doorway, he sees a woman, Lady Macbeth, standing there. She has a glazed look in her eyes, she’s holding a cleaver dripping with blood, and her hands are covered with blood as well. Shakespeare slips surreptitiously into a phone booth, calls the police, and emerges, brandishing a gun. He tells Lady Macbeth that if she moves an inch he’ll blow her head off. In fact, Lady Macbeth works at the Titus Andronicus Butcher Shop, and she didn’t have a chance to wash her hands before she left work. However, when she tries to tell Shakespeare this, he thinks it’s a pile of baloney, and doesn’t let her go until the police arrive. She sues Shakespeare for false imprisonment. Can he defend on grounds of legal authority? _________________
