The 2002 edition of Injury Facts from the National Safety Council reports the following statistics :
It is difficult to provide a specific number as justified shootings can vary depending on legal definitions and circumstances. However, according to the CDC, in 2019, there were around 15,000 homicides by firearm in the United States. Justified shootings would be a subset of this total number.
On average, there are about 15-20 icicle-related deaths per year in the United States. These deaths usually result from icicles falling on individuals or causing accidents due to slippery conditions they create.
Thousands, and it will keep on happening until people realize that this is not the wild west where the only way of settling things was by shooting, the problem is that some people think it is their God given right to use a gun for "protection" isn't that a hoot? Protection from what, from other people running around with guns!! And so it goes......
Assault rifles are responsible for a small percentage of gun-related deaths in the US each year, estimated to be less than 500. However, the overall number of deaths caused by firearms, including handguns, is much higher, with approximately 40,000 deaths annually.
Around 8 million people die each year due to smoking-related causes, according to the World Health Organization. These deaths include both direct smoking-related illnesses like lung cancer and heart disease, as well as deaths due to exposure to secondhand smoke.
