Perhaps you are not condoning murder, but in this case do you find justification in this particular murder?
First, the term murder prejudges the action.
One student did use deadly force. The question should be, “Was deadly force justifiably executed?”
Some 30 years ago, within a generation, deadly force was justifiably used in the prevention of a felony.
We have decriminalized many activities so as not to judge others, but such decriminalization simply fails to adequately discriminate between legitimate and illegitimate behavior.
Who is more ethical, the boy who used deadly force or the generation which denied him his God given rights of not having to accept aggressive homosexual assault upon his person?
