Police use of force & outcomes Feb. 2012 report
A new report, from research funded by the Department of Justice, examined eight police agencies, (Columbus, OH, Charlotte-Mecklenburg, NC, Portland, OR, Albuquerque, NM, Colorado Springs, CO, St. Petersburg, FL, Fort Wayne, IN, and Knoxville, TN) and examined how different policies changed law enforcement strategies.
Researchers found that there is no ideal (or flawed) policy approach across all outcomes, but the report offers ranking and outcomes for each policy offered allowing police executives to choose the best route for their force.
