I found a website from a company that make a living specializing in that:
- https://www.aftermath.com/content/accidental-shooting-deaths-statistics
It is more or less an advertisment for their 'cleanup after' business, so I would expect some exaggeration.
But here is the question: Which way would they want to exaggerate?
- Would they play down the danger? to make more people need their services.
- Would they exaggerate the danger? to make fewer people need their services.
I see no real need for them to exaggerate in either direction. As long as people know they exist they will have customers who need their services.
And by just existing they prove it is not all that rare.
The page mention 3,800 fatal shooting accidents in a 6 year period. some 600 pr year or a bit more than 2 a day.
Is that too many?
