President Obama's choice for defense secretary, Chuck Hagel, actually illuminated one of the weaknesses of the gun control case. Hagel had been closely associated with Global Zero (though he's since repudiated it), a movement dedicated to "the elimination of all nuclear...

a noise disturbance is not any lethal threat,so you have ZERO right to shoot the person making the noise. So much for your idea of "responsible".
