I just had a hardcore libertarian friend who is the father of a young child post that yes, he's a hardcore libertarian, but he thinks that we need to revisit the 2nd Amendment and bring it out of 1791 and into 2012. On one hand,
for recognizing that maybe the founding fathers didn't foresee the high capacity semi-automatic weapons we have today when they drafted the Bill of Rights. On the other hand,
for thinking there's any chance of "revisiting the 2nd Amendment" in today's political climate.
On a side note, what are the odds of the Constitution being amended for any reason in any of our lifetimes? 2/3 vote of both houses of Congress plus ratification by 3/4 of the states... I'd give better odds to the Chicago Cubs threepeating, or someone proving P=NP.
