FBI justifiable homicide data indicates that police officers may be safer in states where law-abiding citizens are empowered to carry concealed handguns in public.
Each year, the FBI publishes violent crime data collected from state law enforcement agencies. This publication includes justifiable homicide (JH) totals for both law enforcement and private citizens.
In its Uniform Crime Reporting Handbook, the Federal Bureau of Investigation (FBI) defines justifiable homicide: Certain willful killings must be classified as justifiable or excusable. In UCR, Justifiable Homicide is defined as and limited to:
· The killing of a felon by a peace officer in the line of duty.
· The killing of a felon, during the commission of a felony, by a private citizen.
Based on the statistics, police officers in non-RTC (Right-to-Carry) states had to defend their lives from violent criminals nearly three times as often as officers in RTC states.
FBI data shows that in 2007, the average violent crime rate for RTC states was 400.5, and their average murder rate was 4.9 (per 100,000 population). The average violent crime rate for non-RTC states was 524. and their average murder rate was 6.8.
These data indicate that police officers’ lives in non-RTC states are in greater jeopardy from violent criminals who have no compunction about attacking police [or the general public]. An armed citizen is less likely to become a violent crime statistic. This data also makes it clear, an armed public also make a police officers work environment more safe.
In Right-to-Carry states, private citizens have greater freedom to defend themselves in public. Because the ratio of justifiable homicides by police and citizens is more balanced, and because the level of police defensive justifiable homicide is lower, one can only conclude that armed citizens are adept at self-defense, enough to provide a quantifiable level of protection for law enforcement. In non-RTC states, the reduced self-defensive capability of the citizenry correlates with higher rates of violent crime and a more dangerous work environment for police officers. (Source)
