The numbers of defensive gun uses (DGUs) each year is controversial. But
one studyordered by the CDC and conducted by The National Academies’ Institute of Medicine and National Research Council reported that, “Defensive use of guns by crime victims is a common occurrence”:
Almost all national survey estimates indicate that defensive gun uses by victims are at least as common as offensive uses by criminals, with estimates of annual uses ranging from about 500,000 to more than 3 million, in the context of about 300,000 violent crimes involving firearms in 2008.

one recent
Washington Post story reported that,
“For every criminal killed in self-defense, 34 innocent people die”:
In 2012, there were 8,855 criminal gun homicides in the FBI’s homicide database, but only 258 gun killings by private citizens that were deemed justifiable, which the FBI defines as “the killing of a felon, during the commission of a felony, by a private citizen.” That works out to one justifiable gun death for every 34 unjustifiable gun deaths.
However, this comparison can be misleading. An armed civilian does not have to kill the criminal in order to save an innocent life. As the
National Research Council notes, “[E]ffective defensive gun use need not ever lead the perpetrator to be wounded or killed. Rather, to assess the benefits of self-defense, one needs to measure crime and injury averted. The particular outcome of an offender is of little relevance.”
