The realm of law and order is not unlike the fashion world in that over time, new trends emerge and fresh items of interest arise, while established trends can be played down or may fall out of favour entirely. Interpretation matters most, and that interpretation is generally subject to the linguistic evolution and societal attitudes of the period. In the case of the 2nd Amendment, the legislation has been furiously debated in a modern setting as to the merits of its grammatical structure and meaning, other historical precedents, and differences between the original and ratified versions.
The recent push for widespread ‘freedom’ enshrined in law as permitting individual gun ownership wasn’t always so. Up to the turn of the 21st century, it was widely accepted by many (even conservative Chief Justice Warren Berger) that an individual right to bear arms wasn’t a thing. Many conservatives at the time carried the same torch and stood in opposition to what they believed was a silly, if not fairly hazardous, idea.
