This is what the Second Amendment gets us: Three times the rate of firearm homicides than any other developed nation (ex-the narco states like Mexico and Colombia) each year. Take an average town of 100,000 people and kill three people every year, for that is the statistical trend we are experiencing in this country. If you wanted to find a solid case for American exceptionalism, you just found it. We are exceptional at killing each other and doing nothing meaningful to stop it.
…[W]hen it comes to gun homicide, the U.S. stands out from the rest of the world’s wealthy nations. According to homicide data collected by the UN Office on Drugs and Crime, and compiled by The Guardian newspaper, the U.S.’s annual gun homicide rate of 2.97 fatalities per 100,000 people is triple the rate seen in most of the world’s other wealthy nations, defined in this chart as countries belonging to the Organization for Economic Cooperation and Development. It excludes Latin American countries like Mexico that have traditionally had high murder rates, often due to political instability and the drug war.
Harvard University’s Injury Control Research Center weighs in here with a collection of research on the prevalence of firearms and the link to their criminal use. Basically its review of the academic literature comes down to this:
Where there are more guns, there are more homicides.
The academic evidence shows strongly and definitively that this is true across the U.S. and other high-income countries, and also on a state-by-state basis within the U.S.
