Firearms (ops Arms) was used rather than weapons suggesting some level of consideration here. They had cannons and warships back then. That bit about a well regulated militia suggests limits on what exactly was permissible.
But obviously we don’t have direct knowledge of every conversation.
> 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;
The point about cannons and warships actually makes it very clear about what the authors' intent was re: balance of risk; at the time, private ownership of artillery was completely legal and unregulated. Private citizens owned warships with dozens of live cannons that could bombard coastal cities, and didn't even need to file paperwork to do so! A warship can cause quite a bit more mayhem than a glock.
