Subsequent to Florida’s enactment of the first castle doctrine law in 2005, no less than 22 additional states have passed some sort of legislation that allows civilians to use deadly force to protect their property from violent and nonviolent offenders. Given the pervasiveness of these legislative acts, it becomes increasing important to find out whether or not they achieve their manifest goal of reducing the amount of crime within a jurisdiction. Toward this end, we employ interrupted time series modeling techniques to assess the impact of Oklahoma’s Stand Your Ground Law on the number of residential and non-residential burglaries. The findings indicate that while the legislative initiative achieved its manifest goal of reducing the number of residential burglaries, it simultaneously had the unintended consequence of increasing the number of non-residential burglaries.
