Well said; point well made.  Killing may be done only to protect life against attack by an unjust aggressor.  What Magliano seems not to get --- and by this time in his life, he seems to consciously avoid --- that Jesus never taught us to refrain from using deadly force against someone who is about to shoot or stab our children.  The notion that we should is not only NOT taught by Jesus, but is so contrary to instinct and reason that I doubt the bona fides of anyone who takes the position that Magliano does.
