Dan Quan, a co-worker of mine, spoke about his experience as a police officer, and the mentality he saw from other officers, in his talk at Rocky Mountain Ruby, "Policing and Pairing: An Unlikely Preparation" (https://www.youtube.com/watch?v=NgGaO92oIGg https://www.youtube.com/watch?v=NgGaO92oIGg).
