“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.”
When the 2nd Amendment was written there wasn’t a standing professional military.
Now there is.
The nonsense passing for militias in 2019 are highly unregulated, unnecessary & completely useless against a modern professional military.
They don’t have the ability to secure a free state.
