The Second Amendment was written as if James Madison had a sudden bathroom emergency at the outset and never got back to it. Eventually, it seems, he stuck it in with the other nine amendments in the Bill of Rights and hoped no one would notice his lame effort.
The entire twenty-seven words of the 2A: "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
We're pretty good at reading comprehension. Call us crazy, but we're not seeing "anyone can carry whatever kind of gun they want, wherever they want" in that sentence. Maybe if we only cared about the last fourteen words, but that's not how sentences work- the first thirteen count, too.
In 1791 the nation did not yet have a standing army. Well regulated militias were necessary to defend the state, just in case. Militia members were permitted arms. It seems to us that Madison was describing the National Guard. In any case, arms at that time were simple single shot muskets, not the high capacity killers that exist today. What are we missing? How can any reasonable individual justify our gun laws by pointing to the Second Amendment?
