If not for gov't, guns would likely be far less in number. So called assault weapons may not even exist at all. Without gov't, how does Eugene Stoner get the experience and jobs from which he designs and build what will become the M-16 which serves as the platform for many of today's so-called assault rifles? Stoner got his experience as a machinist working for a WW2 aircraft armament company which lead to his design ideas, Armalite and the rest is history. One could easily learn the same of a John Browning or Mikhail Kalshnikov who ironically wanted to be and was also a poet with 6 published works of poetry.
If one wants to start to go to the root of the violence problem, there you go. What, Where, When, Who and Why? The how part is back to gov't.
Think about it.
Then again, I'm betting neither side of this argument wants too!
