Yes, the article I posted contained these lines:
The shorter life expectancy for Americans largely was attributed to high mortality for men under age 50, from car crashes, accidents and violence.
The report's authors were particularly critical of the availability of guns, writing: "One behavior that probably explains the excess lethality of violence and unintentional injuries in the United States is the widespread possession of firearms and the common practice of storing them [often unlocked] at home."
It's all there.
