Well that's the funny thing about the second amendment isn't it. It's not up for debate. And it especially isn't open for debate when people wander in and stat spewing some idiotic platitude about society and gun access.
And besides that, do you even remotely know how easy it is to build a gun out of just commodity pipe? In fact Canada and Australia is having kind of a problem with home made copies of the old MAC-11 9mm SMG. Gun access isn't the problem. It's uncontrolled urban crime. And that's not going to change until people stop trying to blame the 100 million otherwise legal gun owners for the acts street thugs in democrat controlled cities.
