Everyone who's worked for any large organization knows that when your boss decides he doesn't like you, you're toast.

When The Man knocks on your door at midnight, he won't be there to arrest you for murder or blasphemy. He'd just like to ask you a few questions down at headquarters. He will call you "sir."
