Give me an example of anything that isn’t “open to interpretation”, or is less open to interpretation than
“The right of the people keep and bear arms shall not be infringed”.
Your critique is without merit. There is no language that a legislature or court will not interpret. There are ample examples of extremely precise and direct language being ignored.
This.
You could write up a sample second amendment that you think would cover every possible contingency. It would be 10k words long and there would STILL be individual words in there that courts would try to parse.
