You know what they say; 'There are lies, damned lies, and statistics'..
The catch in your's is 'gun deaths'. Lets see the same chart on 'homicides' 'Violent crime' etc..
We already know where the US stands on those. Very safe. Extraordinarily safe if you take out the democratically controlled, innercity cesspools of Detroit, Chicago, DC, etc..
If you're dead, and someone murdered you, how you got that way is pretty irrelevant.
If you take out suicide and 15-30 year old inner city minority males that didn't' graduate high school and do use drugs, killing one another; our gun violence level is really not worth discussing. If gun control is still the way to go in Chicago, et al; I really don't care what they do, within the levels of control that SCOTUS has deemed constitutional. But I'm not going to submit to some One-sized-fits-all, top down, DC approach. Rural Montana is not the south side of Chicago.
The AR15 mass shooting that dominates the media is an outlier. ALL rifles account for so little of gun deaths its negligible; and of that subset; ones with features like plastic stocks and pistol grips that induce paranoia account for even less.
Of course none of this matters; because rights are not subject to statistics. Good thing, because freedom of RELIGION, association, and speech - probably in that order- have killed more people than guns ever will.
The thing about the gun argument is that there are plenty that will kill to keep their rights, or what they perceive their rights are.
There are very few that are willing to kill or be killed to take those rights.
So, I predict this conversation will remain on the internet as a hypothetical and as a political talking point for a bunch of pussies that 'work' in DC
