The sudden and tragic suicide of a law enforcement officer can be devastating, leaving the department, family, and loved ones in shock. In order to provide the necessary support during this difficult time, it is crucial for the executive level and command staff to know how to respond effectively. However, without access to reliable research and evidence-based strategies, it can be challenging to determine the appropriate course of action. Developed by the International Association of Chiefs of Polices, National Officer Safety Initiatives, EDC Learning Transforms Lives, and the National Action Alliance for Suicide Prevention, After a Suicide in Blue: A Guide for Law Enforcement Agencies aims to address this issue by outlining best practices in suicide prevention. It offers guidance on immediate steps to take after a suicide loss and suggests support services that should be made available in the long term.
