What happened in Colorado was not an exception. It was inevitable. It will keep happening, one bullet at a time, every single day. And each time it does, that will be the price some innocent person will pay for us not bringing the Second Amendment up to date. For us not recognizing the obvious: that the society of 1789 is very different from the society of 2012 when it comes to guns. The Framers gave us the power to change the Constitution in these kinds of situations, and we have the responsibility to do that. If that makes you feel paranoid, you can deal with that problem by talking to a good therapist.
