I always love discussing "The Founders never could have forseen..." with those who claim that we're only allowed flintlocks.
Actually, there's some solid documentation that the Founders envisioned people having a
lot more than flintlocks.
In the U.S. Constitution, Article 1, Section 8, lists, among the other powers of Congress, the power to " . . . grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water;"
Letters of Marque in the 18th century were intended to legitimize privateers to act in a warlike manner against a government's enemies; in other words, the Founders envisioned and allowed for private ownership and operation of
warships on the high seas! Much more than mere muskets . . .
Perhaps this should be revisited if and when the question of how to deal with pirates in places regular navies aren't interested in intervening. (e.g., offshore from Somalia.)
