What part of “...shall not be infringed.” do they not understand?
In Pennsylvania, it’s “shall not be questioned”...but that doesn’t stop them!
They understand they haven't yet been tarred and feathered, so they assume they can infringe all they want.
I think it is significant that this amendment wasn't written to say, "The Congress shall make no law ...". The prohibition is even stronger ... the right of the people to keep and bear arms shall not be infringed. I think "by anyone" is implicit in that wording.
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.
What part of “...shall not be infringed.” do they not understand?
It's not the "...shall not be infringed.” part. It's "...the right of the people..." part that will settle this once and for all.
Abbrogate that statement in the second will mean that the very same statement, ""...the right of the people..." is also meaningless in the 4th, 9th and 10th amendments.
So, it ain't gonna happen.
