We explore the policy feedback process and describe how state policies have evolved or devolved in the specific issue area of firearm laws and domestic violence. This chapter demonstrates how and when states respond to the need to reform their domestic violence laws and shows how key actors in that process, including legislators and interest groups, affect the content of the policy that is adopted. The chapter includes examples of states whose definition and scope of domestic violence laws vary and contrast them with each other and with federal law. We present six studies of states that differ in their legislative histories on domestic violence laws to identify key factors that can explain this variation; we test these factors in the quantitative analysis presented in Chapter 4.
