People of all ages die from all sorts of irresponsibility every day, yet many continue to focus on firearms even though other issues kill far more every year.
In 2010, about forty thousand deaths by suicide occurred in the United States. Only about half of those were from firearms. ( 19,392 actually )
The CDC states there are about eleven thousand homicides by firearm in the United States in the same year.
While noteworthy, those numbers aren't even playing the same game as the issues that really kill us in large numbers:
Heart disease: 611,105
Cancer: 584,881
Chronic lower respiratory diseases: 149,205
Accidents (unintentional injuries): 130,557
Stroke (cerebrovascular diseases): 128,978
Alzheimer's disease: 84,767
Diabetes: 75,578
Influenza and Pneumonia: 56,979
Nephritis, nephrotic syndrome, and nephrosis: 47,112
Intentional self-harm (suicide): 41,149
So, while the intentions are good, focusing on firearms as a high priority issue is a bit misguided when considering the numbers above. We would do a lot more by pouring money into medical research if saving lives is truly the goal.
