The statement was actually made by a Lt. Gen. (relaying a remark he heard), with Tom affirmatively replying (from Journey into Darkness, p.52):

LG Owens: If they have a gun, shoot 'em. If someone picks up the gun, shoot him too. Keep shooting until no one picks up the gun.

Tom: Sir, that is exactly what needs to happen.
So, let's adopt that ROE "exactly" (literally) for use worldwide. One result would be the likely deaths of Tom and me; each of us owns guns, and based on perceived character wouldn't comply with a mandate to give them up.

Or, are we "good guys", who for some reason are exempted from the literal rule ? Or, do we live in a "good" country, which for some reason is exempted from the rule ? Or, is there something missing from what should be called "Owens' Rule" ?
