Upon careful re-reading of the 2nd Amendment, I cannot find a reference to any "requirements"...
I must have a defective copy...
“Well regulated.” In modern vernacular it means “well functioning.” If you are a mouth breathing moron who goes around shooting people because of an argument, that’s not well functioning and you’ll end up in prison.
I’m not referring to government regulation here, I’m referring to the duty that we have to the Constitution to know the law and to be well functioning.
Try to read.
