Rifles, muskets, longbows, and hand grunades are inherently democratic weapons. A complex weapon makes the strong stronger, while a simple weapon — so long as there is no answer to it — gives claws to the weak. George Orwell, “You and the Atom Bomb”, 1945 How does “giving claws to the weak” relate to “Life, Liberty and the Pursuit of Happiness” and our understanding of social contracts, CJUS legitimacy, and/or criminal law?
