“When I go to the range, my intention is to place every round in the Bulls-eye; thus where the lead actually goes really doesn’t matter - right?”
I do not understand your point. Please elaborate.
I believe what Hodar was inferring is that shot placement is king.
This study is a classic correlation does not prove causation study.
"Legal intervention" shootings are probably more fatal because they are being performed by people who are trained to shoot for center of mass, and to continue to shoot until the threat ends. They also practice several times a year or more to refine these skills.
Most of the intentional (assault) shootings are most likely performed by untrained individuals who rarely if ever practice, so shots are more likely to be in non-lethal areas such as arms and legs.
Of course, shot placement depends a great deal on intention. Skill is only part of the equation.
A person who does not intend to kill is unlikely to aim for the center of mass.
Do you really think differences in intention produce random results?
