Here are some of the highlights:

  • “Best Practices and Training Guide”: In a document dated May 30 2014, PredPol recommends “broken windows” policing. Broken windows is a controversial, unproven method of policing which postulates that harshly penalizing petty crime will improve safety in cities overall.
