Quote from Lepore's opinion on 2A -
The English words "bear arms" were used for a specific reason in the second when it was written. Again, the British crown didn't stir much, if at all, regarding the subject of restricting small arms ownership or use in the colonies, before, or even during the revolutionary war. They did however take specific measures to seize artillery and its associated equipment and ammunition, in fact that was when the first shots were fired in the war for independence. Nor was there any particular movement to restrict small arms by the new American government. So why even write "bearing arms, people, militia" into the second amendment then? The British military terminology "to bear arms" being included, as "arms" as was used then didn't refer only to small arms, in fact it specifically was a term used to describe the most powerful weapons of the day on the battlefield, which was field artillery.
