Law Enforcement Use of Force SIMEX Resources


In April 2021 HSSEDI, sponsored by the Department of Homeland Security (DHS), Office for State and Local Law Enforcement (OSLLE) and at the request of nation-wide law enforcement agencies, conducted the Law Enforcement Use of Force (LE UoF) Simulation Experiment (SIMEX 21-3). The goal was to provide evidence-based data and recommendations to the law enforcement community of practice that would support the deterrence and reduction of arrest-related fatalities and injuries due to applied force by officers.  

For a general overview of the experiment, watch the SIMEX 21-3 Overview and Highlights Reel.

Below are the associated publications and findings. For a copy of the SIMEX 21-3 Final Report, which provides an overview of the experimental design, data analysis, conclusions, and recommendations, please contact hssedisimex@hq.dhs.gov.
