From Ammoland:

Contrary to what President Biden keeps babbling on about cannons, the Second Amendment “right of the people to keep and bear arms” was considered comprehensive at the time of the founding. Civilians could and did own cannons, repeating rifles, and even warships armed with cannons. In his ridiculous decision in the Dred Scott case, explaining why dark-skinned people of African heritage could not be citizens, Justice Taney infamously rolled out his “parade of horribles,” saying that if African-Americans were citizens, they would be able to freely travel between states, hold political meetings, and carry arms wherever they went.
