CLAYTON CRAMER: Why the FBI’s Justifiable Homicide Statistics are a Deceptive Measure of Defensive Gun Use. “As part of the FBI’s Uniform Crime Reports system, the FBI gathers and reports both civilian and police officer justifiable homicide statistics. The methods by which these numbers are gathered make them gross undercounts of the actual legal, defensive homicides by citizens. Furthermore, comparing the civilian justifiable homicide numbers to criminal homicides for public policy cost/benefit analysis understates the crime reducing effects of civilian gun ownership.”
