. . . Trayvon Martin would not have been shot. On the other hand, had he been unarmed, it is highly likely that Zimmerman would be either dead or permanently injured.
So much for the fallacious 'disproportionality argument.'
If you attack me with deadly force and I reply with deadly force of greater magnitude, your relative weakness does not supply one iota of moral justification for your attack, nor does it subtract one iota of moral justification from my defensive response. If I am justified in using deadly force against you as aggressor, then the fact that my deadly force is greater than yours does not (a) diminish my justification in employing deadly force, nor does it (b) confer any justification on your aggression.
Suppose a knife-wielding thug commits a home invasion and attacks a man and his family. The man grabs a semi-automatic pistol and manages to plant several rounds in the assailant, killing him. It would surely be absurd to argue that the disparity in lethality of the weapons involved diminishes the right of
the pater familias to defend himself and his family. Weakness does not justify.
The principle that weakness does not justify can be applied to the Israeli-Hezbollah conflict from the summer of 2006 as well as to the Israeli defensive operations against the terrorist entity, Hamas. The principle ought to be borne in mind when one hears leftists, those knee-jerk supporters of any and every 'underdog,' start spouting off about 'asymmetry of power' and 'disproportionality.' Impotence and incompetence are not virtues, nor do they confer moral justification or high moral status, any more than they confer the opposite.
