Think of government as a paranoid Hydra with all its heads turning in different directions to peer into the shadows created by its own movements.
If we are not dependent on, and afraid of, the monster then we might actually learn we don't really need it. The government Hydra is a thing of myth...it just doesn't want to accept that fact. So to keep us from entering the cave and putting it out of its misery it roars and spouts smoke. And occasionally eats someone.
