A study conducted by the National Academies Press on firearm-related violence shows that not all Americans who own guns have murderous intentions. The institute was requested by an executive order from President Obama to investigate the topic in light of the Sandy Hook shootings. There were many positive points about gun ownership in the study. It concluded that most gun deaths in the US are due to suicide, not violent crimes. It also proved that mass shootings are one of the rarest forms of violent crime in the country, and that self-defense happens at least as much as violent crimes do. This disproves the main argument from gun-control advocates that using guns self-defense almost never occurs. To see the full study, please click here.
