This information may also be helpful in efforts to educate your community. In a recent conversation with Force Science News, Lewinski enumerated 10 limitations that are important to keep in mind regarding body-camera evidence (and, for the most part, recordings from other cameras as well) if you are an investigator, a police attorney, a force reviewer, or an involved officer.
