You make an excellent point. And if we take a word for word interpretation of the 2nd Amendment, let's look at what type of "arms" were available to citizens at the time the Amendment was written: muskets. So, you can buy and own all the muskets you want, I don't even care if they do a background check on you or not, when you buy your musket. But when you get in line to buy a weapon that can kill twenty people in the blink of an eye, maybe we should apply a bit of common sense, with things like background checks. And God forbid we make them take a shooting and safety course or attain some type of certification.
