Slave Patrols, the Militias of the Second Amendment
Something that Thomas Jefferson did say, in the proposed Virginia Constitution, in June of 1776: "No freeman shall ever be debarred the use of arms."
The text of the Second Amendment to our United States Constitution:
"A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms shall not be infringed."
The words "well regulated Militia", "security of a free State" and "freeman" are key in all this.
During the debate around the writing of our Constituion, the issue of slavery, our original sin, was constantly present, though rarely referred to in name. Thomas Jefferson, Patrick Henry, and others were concerned, though, with a potential threat to the existence of the militias, the slave patrols, consisting of freemen, that were maintained in Virginia and other slave states in fear that those they enslaved and considered property might rebel.
The Second Amendment was part of a compromise and worded carefully to allay those fears.
Here is a link to the best treatment that I have read on the subject so far:
