> Firearms was used rather than weapons
Where? The constitution says neither. It says "Arms"
Regardless, the constitution specifically makes reference to the private ownership of cannons and warships.
> To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water;
Arms at the time meant man portable weapons as distinct from cannons or trebuchet etc.
Just posted about firearms so many times used the wrong word here.
