Pretty sure our founding fathers, many of whom were brilliant men who also had a very pronounced pedagogical interest, would not stand for it when people said to them "But the constitution you wrote protects the right to buy multiple weapons, semi-assault rifles, ammunition clips and carry them wherever and in some cases even concealed!" I'm supposed to believe Thomas Jefferson who went to great lengths to found what is now the University of Virginia, in the wake of the Viriginia Tech shootings would say "Hey, nothing we can do..." Or that people like John Adams, extremely learned, would say "Hey they are just crazy people! Watchagonnado bro? People is bad!" Our founding fathers were obsessed with looking at what other countries were doing, with studying history, with comparative government, with picking the best things, expanding on them, learning, PROGRESS... but yeah, they wrote the Constitution, added the Bill of Rights, and then figured "That's it! Done for eternity! Never to be bettered!"
