Do military and police personnel differ in their views of acceptable uses of violence? In this paper, we utilize data from an original survey conducted within the security institutions (police and military) in ten countries to assess whether or not institutional differences within police and military institutions influence personnel's views towards restraint, the seriousness of misconduct, the likelihood of reporting misconduct, and the likelihood of escalating behavior in hypothetical scenarios. Our results support our hypothesis that police are more likely to demonstrate restraint, more likely to report misconduct, and more likely to view misconduct as serious. Contrary to our expectations, we also find that police personnel are more likely to engage in escalatory behavior in the hypothetical scenarios we present to them. Furthermore, we find that police personnel who have deployed on a United Nations (UN) peace operation are most likely to exhibit these characteristics. This research has important implications for our understanding of the tendency of security forces to engage in misconduct, both domestically and while deployed on a peace operation.
