Police follow a code that is not unlike that followed by groups that they have legal authority over. When one officer refuses to be an accomplice to a crime committed by another officer, the officer is culturally pressured not to act in a way that would attack the offending officer. One reason for this is you ought not throw stones when you live in a glass house. Officers commit crimes for all sorts of reasons: mistakes, shortcuts, aggression, revenge. Further, if officers blew the whistle on each other for every matter, the culture would turn to disrespect and distrust among those whose lives depend on each other. So, Baltimore ends up with much greater problems as smaller ones snow ball. Body cameras are helping to distance officers from hurting their team but they're not being managed in a way that will ensure integrity. The fox can't guard the hen house. Police control when the cameras are on, they control the recordings, and they control who reviews the recordings. I might as well add that Trump is in the process of creating this culture among the branches of government. Smaller problems won't be reported. Much greater problems will eventually emerge. Everyone will ask how this could ever happen. A political savior will swoop in and reform.
