My thoughts on the 2nd are the same as the authors of these quotes.
“The right of the citizens to keep and bear arms has justly been considered, as the palladium of the liberties of the republic; since it offers a strong moral check against usurpation and arbitrary power of the rulers.”
– US Supreme Court Justice Joseph Story, Commentaries on the Constitution 1833
“A strong body makes the mind strong. As to the species of exercise, I advise the gun. While this gives a moderate exercise to the body, it gives boldness, enterprise, and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body, and stamp no character on the mind. Let your gun therefore be the constant companion of your walks.”
— Thomas Jefferson, 3rd President of the United States, From a letter to nephew Peter Carr, Paris, August 19, 1785
