Do you have a link to the full study? All I can find are the summary conclusions, and a link requiring payment for the full report and methodology.
I'd truly be curious as I'm skeptical of their conclusions regarding statements such as background checks for ammunition purchases could reduce the mortality rate to 1.99 per 100,000. How was this determined?
I'd also be curious how much of this would be attributed to suicides. Now, I'm not exactly pro-suicide but with regards to gun stats I can't find myself too worked up about it. Whether the presence of a firearm makes it easier for someone to off themselves shouldn't, in my opinion, be much of a consideration.
