There are mission statements, policy, then there is the way things are done. I have personally seen the dozens of moving parts involved in allowing police to get away with murder. Start with the police car. I have found the 'throw down weapons' the police use when they kill an unarmed man, woman or child to establish provocation and self defense. It is ususlly a 6 inch knife. They do not always bother to put a victims fingerprint on it when it can be done later. Then there is the report - enough said. Then there is the police union and the DA...
The code of silence has a murder threat behind it. If you don't stay silent we will allow you to be killed or die if you ever need assistance. Lynching AND lynching by othermeans hasbeen part of the US for a 100 years. Hopes and prayers was what MLK was about. America is fed up with hopes and prayers and frankly don't want to hear them anymore. Only action, law and convictions are going to be heard
