Does the right to bear arms extend to all Americans or only "A well regulated militia?"

There's an argument that any able-bodied person was considered to be a part of a militia. There's also the argument that Washington called for a militia only until a standing military could be established.

Doesn't really matter. The Constitution is a framework, a document open to interpretation by design. France updates its constitution every two years. England doesn't even have one. The US Constitution is not the direct infallible word of God.
