Late one night, a husband was asleep in bed with his wife, and his two children were asleep in their rooms. The husband was then awakened by a noise coming from downstairs. The husband reached for his licensed handgun, which he kept in a nightstand beside his bed, and crept downstairs. The husband saw a burglar in the den, trying to open the wall safe. The burglar, hearing the husband's steps, whirled around and pointed a gun at the husband. The gun was not loaded and was merely intended to intimidate anyone who confronted the burglar. The husband, fearing for his own life and the lives of his wife and children, fired his gun, hitting and killing the burglar. If charged with murder, does the husband have a viable argument for self-defense?
