LESSON NO. 1: If a bureaucrat, or a soldier sent by a bureaucrat, comes to knock down your door and take you someplace you do not want to go because of who you are or what you think -- kill him. If you can, kill the politician who sent him. You will likely die anyway, and you will be saving someone else the same fate. For it is a universal truth that the intended victims always far outnumber the tyrant's executioners. Any nation which practices this lesson will quickly run out of executioners and tyrants, or they will run out of it.
LESSON NO. 2: If a bureaucrat, or a soldier sent by a bureaucrat, comes to knock down your door and confiscate your firearms -- kill him. The disarmament of law-abiding citizens is the required precursor to genocide.
LESSON NO. 3: If a bureaucrat tells you that he must know if you have a firearm so he can put your name on a list for the common good, or wants to issue you an identity card so that you be more easily identified -- tell him to go to hell. Registration of people and firearms is the required precursor to the tyranny which permits genocide. Bureaucrats cannot send soldiers to doors that are not on their list.
