Originalism sounds like a crock.In the context of United States law, originalism is a concept regarding the interpretation of the Constitution that asserts that all statements in the constitution must be interpreted based on the original understanding of the authors or the people at the time it was ratified. This concept views the Constitution as stable from the time of enactment and that the meaning of its contents can be changed only by the steps set out in Article Five.[1] This notion stands in contrast to the concept of the Living Constitution, which asserts that the Constitution should be interpreted based on the context of the current times, even if such interpretation is different from the original interpretations of the document.
That is the Wiki. I have several dictionary
I can't wait for Gorsuch to opine that "the original understanding of the authors or the people at the time it was ratified" means that the Second Amendment was never intended to protect any weapons except blades, clubs and muzzle loading guns and cannons.
