For people who are concerned about police encounters, I recommend the “Audit the Audit” series on YouTube. They show actual police-citizen situations while commenting on the legality of the officers’ actions. They also present the involved state law. At the end of many videos they present a grade for each person involved.
The makers of these videos highly recommend that citizens record police encounters. They also invite anyone to share their videos with Audit the Audit.
