So I guess, more simplistically, you want to do another "luxury tax" so to speak.  Tax the owners of luxury boats so high, they stop buying boats.  Not because there was a problem, but because most people can't afford one so to make it "fair", the left successfully lobbied Congress and the law was passed.  Murphy's law kicked in and it turns out, boat building businesses went out of business.  So too, based on your statistic, gun manufacturers will close up shop.  Maybe not the big ones.  So your effort to "fix" this issue based on "feelings" and not reason will adversely affect legal gun owners, gun manufacturers, gun accessory manufacturers, truckers who move the product, stores that sell the product, and on and on throughout our economy....why?  because the left is incensed and feels, "Well.....we GOTTA do something!"  You see, now I have given your side more ideas.  Shame on me.

Focus on "gun deaths" in the chart.  Most were from suicides & black on black crime.
