My first class in criminology in 2005 was "Ethics for Criminal Justice" at Washtenaw Community College. Initially, the syllabus said that we were going to look at police corruption in New Orleans, but Hurricane Katrina hit, and our instructor wanted to give the city time to recover. The irony is inescapable.
In 2008, completing a bachelor of science in criminology at Eastern Michigan University, I had a required senior class in police organization. For both that first and last class my research into police corruption found that it is known everywhere, and some places have more of it than others. That opens a sociological or anthropological investigation: why do cultures differ? Physical environment and population can be similar, but outcomes can be pleasantly or horribly disparate. While police corruption is known in Minneapolis their police force seems to suffer less from moral failures.
We know at the individual level that female officers write more traffic tickets than do male officers. Females also have statistically fewer complaints lodged against them by the public. Education also makes a difference: officers with college education (2-year or 4-year) write more tickets than those with just high school diplomas. Also, educated officers have fewer complaints lodged against them. It would seem that the ideal police force would be comprised largely of women with college degrees.
