Considering one of the graphs you posted is comparing homicide rates to gun laws, I would ask the same of you.p.s. please stop equating violence with "gun violence" it's extremely disingenuous to pretend that murder when not committed with a gun is somehow more acceptable.
And I am not sure you grasped by point... When crime rates fall, most often, violence crime rates also fall. When violence crime rates fall, you can be almost certain, rates of gun violence have also dropped.
