I encourage people to read the actual study and not form an opinion based on the article itself. Unfortunately, the casual reader probably won't do that and possibly come away with the wrong conclusions. The article, written by the authors of the study, gives the general impression that the conclusions of the study may be the same throughout the country. From the article: "Because body cameras produce an objective accounting of the interactions between police and citizens, they have the potential to overcome previous weaknesses in the quality of evidence." This is a very generalized statement. The Conclusions and Discussion section of the paper is more specific. The study focused solely on the Chicago Police Department. While this research is certainly encouraging, the same results may not be true for other communities and police departments. I think the study authors would all agree that further research is needed.
