Evaluating the determinants of support for police militarization among officers
Politics &Policy, Volume 51, Issue 4, Page 636-660, August 2023., 2023 Abstract We evaluate the determinants of officer support for their agency participating in the 1033 Program: a program that facilitates the flow of military hardware to local law enforcement agencies. In doing so, we provide insight into why officers demand such equipment, which, in turn, may partially explain patterns of program participation and ...

Policy Studies Journal, Volume 51, Issue 3, Page 551-571, August 2023., 2023 Abstract How political actors choose which politics to focus on helps shape the outcome of the policy process. While the policy agenda of the federal government has received widespread attention, there is much less known about the policy agendas of the U.S. states. In this paper, we describe how and why states choose to have similar agendas. We rely on
