Yeah source 3 does not calculate the defensive use of guns.
And if you bother to read the actual study you will find that the group of gun owners studied had higher levels of NON firearm related assault and higher levels of substance abuse , and criminality.
I other words the study was skewed due to selection bias.
So you're telling me that gun owners are not being responsible with firearms because they're not using them responsibly because they're using them in connection with assault, substance abuse and criminality?
Also I would safely say these parts are all related to the defensive use of guns:
"Study findings in one other area were noteworthy: homicides perpetrated by strangers. Homicides of this kind were relatively uncommon in our study population—much less common than deaths perpetrated by the victim’s partner, family members, or friends. But when they happened, people living with gun owners did not experience them less often than people in gun-free homes..."
"
This result clashes with a classic narrative promulgated by gun rights groups: firearm owners use their weapon to turn away or overpower a threatening intruder, thereby protecting home and hearth. We did not detect even a hint of such protective benefits. If anything, our results suggest that cohabitants of handgun owners were
more likely to be killed by strangers, although that result did not reach statistical significance.
A second
study by our team, published in
JAMA Psychiatry on April 29, switched the focus of second-hand risks to suicide in a large sample of women living with handgun owners in California. They were 50% more likely to die by suicide than their female neighbors in gun-free homes, and more than four times as likely to die by suicides that involved the use of firearms.
All of us crave a safer home and community. Mounting scientific evidence indicates that bringing a gun into the home isn’t a step in that direction. On the contrary, if safety is the goal, it’s more likely to be a shot in the foot—or much worse."
