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. Maybe if we just cared about the last fourteen words, but that's not how sentences work- the other thirteen words 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. Arms at that time were simple single shot muskets. What am I missing? How can anyone justify the constitutionality of our gun laws by pointing to the Second Amendment?
