An intruder broke into Gregory Mason’s home at 3:00 a.m. on March 15, 2010, with the intent to steal his expensive and rare coin collection. Asleep upstairs when he heard the noises in the middle of the night, Gregory, armed with a baseball bat, proceeded to beat the intruder nearly to death. He was charged with the crime of aggravated battery and is awaiting trial. Gregory is considering what options, if any, he has as a defense to the crime. If you are Gregory’s defense lawyer, what type of defense would you suggest and why?
