And large caliber weapons kill more people.

A new study published in the journal JAMA Network Open underscores an often overlooked factor in gun-policy debates: When it comes to lethality, not all guns are created equal.
Analyzing data on hundreds of shootings in Boston from 2010 to 2014, Anthony Braga of Northeastern University and Philip J. Cook of Duke University found that on a bullet-per-bullet basis, shootings committed with a large-caliber firearm are much more likely to result in a fatality than those with a smaller caliber gun. Caliber is a measure of the diameter of the bullets fired by a particular gun.
The study analyzed data on 221 gun homicides and 1,012 nonfatal shootings that happened in Boston between 2010 and 2014. On first glance, the numbers provided a confirmation of the depressing demographics of shooting cases: “Most gunshot victims and survivors were young minority men with prior court arraignments,” Braga and Cook found. “Most attacks occurred in circumstances where gangs or drugs played an important role.” Most occurred outdoors in disadvantaged neighborhoods.
But they found stark differences in shooting outcomes depending on the caliber of gun used. They divided the calibers of guns used in the shootings into three categories: small, which included .22-, .25- and .32-caliber handguns; medium, including .380s, .38s and 9mms; and large, including .40s, .44 magnums, .45s, 10mms and 7.62 x 39s.
They then found that all else being equal, a person shot with a medium-caliber weapon, such as a common 9mm handgun, were roughly 2.3 times as likely to die of their wounds than someone shot with a small-caliber gun. Large-caliber gunshots were even deadlier, resulting in odds of death 4.5 times that of small-caliber gunshots.
“The implication,” they write, “is that if the medium- and large-caliber guns had been replaced with small caliber (assuming everything else unchanged) the result would have been a 39.5% reduction in gun homicides” in Boston during the study period.
The results undercut the idea that “guns don’t kill people, people kill people.”
This study shreds the idea that focusing on the mental health of the shooter instead of the types of guns that are available to citizens is the key to reducing gun deaths in this country.
So passing laws to outlaw military-style weapons actually will reduce the number of deaths during mass shootings, who knew?
Oh right, everybody with half a brain.
