The suppression of crime will be accomplished by deterrence. An armed society is a safe society because criminals know that their intended victims are often armed and will shoot them dead in the course of the crime. This is usually done without firing a shot. An armed society is a polite society because people are more respectable when armed than when disarmed. The power imparted to an individual by the possession of a weapon instills a sense of responsibility for his behavior as nothing else can.
People avoid conflict to prevent it's escalation to violence that can be deadly.
We are all more polite to someone that we know to be armed than someone we know to be disarmed. This is a two way street. We cannot respect a person who holds us in contempt. Our governments have held us in absolute contempt for over 65 years in the United States. By eliminating those acts of government that treat us as insane criminals and mentally deficient slaves we force government to come closer to respectability.
