Because a well-armed, well-educated, and well-trained citizenry is the best form of Homeland Defense, and is better prepared to respond to crime, invasion, disaster, terrorism, and tyranny...
Though no authority need be cited for the right of individuals to act in self-defense, alone or in groups, we may direct your attention to the following:
Amendment II to The Bill of Rights
Article 1, Section 6 of The Michigan Constitution
10 US 311 parts A and B
The Hague Protocols regarding the formation and conduct of militias and other volunteer corps
The reader is also encouraged to become familiar with The Founding Fathers' positions and statements regarding the militia.
