Your chart is somewhat misleading. This is from a study completed in 2016 by Chicago Univ.
There are 30,000 gun related deaths per year by firearms. U.S. population at the time was 324,059,091. Do the math: 0.00925% of the
population dies from gun-related actions each year. Statistically
speaking, this is insignificant! What is never told, however, is a
breakdown of those 30,000 deaths, to put them in perspective as compared to other causes of death:
• 65% of those deaths are by suicide which would never be prevented by gun laws
• 15% are by law enforcement in the line of duty or self-defense and justified
• 17% is through criminal activity, gang and drug-related or mentally ill persons – gun violence
• 3% are accidental discharge deaths
So technically, "gun violence" is not 30,000 annually, but drops to 5,100.
Still too many? Well, first, how are those deaths spanned across the nation?
• 480 homicides (9.4%) were in Chicago
• 344 homicides (6.7%) were in Baltimore
• 333 homicides (6.5%) were in Detroit
• 119 homicides (2.3%) were in Washington D.C.
So basically, 25% of all gun crime happens in just 4 cities. All 4 of
those cities have strict gun laws, so it is not the lack of law that is
the root cause.
This basically leaves 3,825 for the entire rest of the nation or about 75 deaths per state. That is an average because some States have much higher rates than others. For example, California had 1,169 and Alabama had 1.
Now, who has the strictest gun laws by far? California, of course, but understand, so it is not guns causing this. It is a crime rate spawned by the number of criminal persons residing in those cities and states.
So if all cities and states are not created equal, then there must be
something other than the tool causing the gun deaths.
Are 5,100 deaths per year horrific? Yes, but how about in comparison to other deaths? All death is sad and especially so when it is in the commission of a crime but that is the nature of crime. Robbery, death, rape, assault all is done by criminals and thinking that criminals will obey laws is ludicrous. That's why they are criminals.
