Information sharing is the lifeblood of policing, yet information/knowledge sharing within and across organizations remains problematic. This article elaborated on previous research on organizational information culture and its impact on information use outcomes in policing by examining perceived impediments to information sharing of 134 officers in three Canadian police organizations. Inductive qualitative analysis of an open-ended question revealed seven mutually exclusive impediment themes: processes/technology, individual unwillingness, organizational unwillingness, workload/overload, location/structure, leadership, and risk management. When viewed from the knowledge management infrastructure perspective, organizational structure was the single most common impediment identified, followed closely by organizational culture. Each organization had unique constellations of information sharing impediments. Recommendations for policy and practice are discussed.
