Fact: Of the 43 deaths reported in this flawed study, 37 (86%) were suicides. Other deaths involved criminal activity between the family members (drug deals gone bad).186
86, Protection or Peril? An Analysis of Firearm-Related Deaths in the Home, Arthur L. Kellerman, D.T. Reay, 314 New Eng. J. Med. 1557-60, June 12, 1986. (Kellerman admits that his study did "not include cases in which burglars or intruders are wounded or frightened away by the use or display of a firearm." He also admitted his study did not look at situations in which intruders "purposely avoided a home known to be armed." This is a classic case of a “study” conducted to achieve a desired result. In his critique of this “study”, Gary Kleck notes that the estimation of gun ownership rates was “inaccurate”, and that the total population came from a non-random selection of only two cities.)
Fact: Of the remaining deaths, the deceased family members include felons, drug dealers, violent spouses committing assault, and other criminals.187
Fact: Only 0.1% (1 in a thousand) of the defensive uses of guns results in the death of the predator.188 This means you are much more likely to prevent a crime without bloodshed than hurt a family member.
