Center for Disease Control did a research on gun violence and conclusions are nothing we don't know.
According to Guns.com,
"Unintentional firearm-related deaths have steadily declined during the past century"
"Mass shootings are a highly visible and moving tragedy, but represent only a small fraction of total firearm-related violence."
"Defensive uses of guns by crime victims is a common occurrence, although the exact number remains disputed" and "when guns are used in self-defense the victims consistently have lower injury rates than those who are unarmed"
