Ah... the essential question about capital punishment.  Mr. Christian, however mistaken he might be, acted in a fashion he felt was "justified" in his own mind.  Perhaps, to us,  that means "evil" perhaps it means "mentally ill."  We condemn him for his actions.  Are we now "justified" in our own minds to take the same actions against him?  ...claiming, of course, that our actions are Right and Just.  We could endlessly debate this question.  Meanwhile, IMO, we need to be sure Mr. Christian is never free again to perpetrate another crime.  Gary Crum
