I ask, sir, what is the militia? It is the whole people except for a few public officials. George Mason
A well regulated militia, composed of the body of the people, trained in arms, is the best most natural defense of a free country. James Madison
The fundamental law of the militia is, that it be created, directed and commanded by the laws, and ever for the support of the laws. John Adams
