Commending Ngoc Le's deed ought not to be misconstrued as an encouragement of vigilante justice. He did what he had to do, on his own property, when his wife faced imminent grievous harm, and only after he gave his assailant an opportunity to live. No civilian in his or her right mind would want to be forced into that life-or-death decision. It is an awful thing to take a human life, no matter how desperate the situation or how despicable the victim.Way too much moralizing. In a survival situation, do what you have to do and move on.
