gun owners place a high value on agency. I have wondered if one reason they tend to not see suicides as legitimate in gun death stats is because they tend to see suicide as a willful act that a person also has a right to. Just a speculation...
I can't read the article, but I would assume that they have not included the suicides happening at home using the car (by inhaling exhaust in a closed space), and have only counted the deaths on the road.
Why?
