Our analysis of HPD summaries found that about once a week on average a Honolulu police officer is suspended or fired for misconduct. Many of these violations include domestic violence, abuse of suspects, lying, falsifying records and even criminal convictions. They are not primarily minor administrative failures or heat-of-the-moment bad decisions as SHOPO suggested.
