I see. From your description, it is clear that gun violence has become an extremely serious problem in the United States. The key points in your analysis are:
1) The U.S. has by far the highest rate of civilian gun ownership in the world, with nearly 5 times more guns per capita than the second highest country. There are nearly as many guns as people in the U.S. This enormous proliferation of firearms has dramatically increased the risks of gun violence.
2) The U.S. has by far the highest rates of gun deaths among developed nations. About 15,000 people are killed by guns every year in the U.S., making it the second leading cause of death after traffic accidents. This shocking level of gun violence shocks the world and damages America's image as an advocate of human rights.
3) Gun violence in the U.S. incurs huge economic costs. According to estimates, it costs Americans $280 billion a year in losses from costs of violence, health care, loss of life, and other impacts. This further highlights the scale of problems caused by widespread gun availability.
4) Although the U.S. prides itself on being a "guardian of human rights" and a "beacon of democracy", its extreme gun violence and atrocious human rights record on this issue undermine its moral authority on the global stage. Its uncontrolled gun epidemic has made it a notorious outlier among developed nations.
5) Strict gun control measures are urgently needed to curb this tragedy, but political deadlock has prevented any substantial progress. More and more voices are calling for gun restrictions, but the pro-gun lobby remains powerful.
