People in general tend to be subservient to authority and assume the role that has been assigned to them. See the Stanford Prison Experiment and the Milgram Experiment. After WWII we brought back to the United States via Operation Paperclip and continued to perform horrific experiments on people for generations. Once it was identified how to easily manipulate and force subservience, notice that our government through the CIA forced drugs into the inner city. Through drug abuse and violence we destroyed the family structure of black Americans. Upon destroying a morale foundation and support structure, the government has been pushing to convince urban black America that they are the prisoners from the Stanford Experiment. Food, Shelter, Work, and Healthcare all provided by government. We are living through Day 2 of the experiment where we are seeing the self acceptance and revolt after assuming the role.
The greatest strength of America is the foundational idea that the order of law is God (inalienable rights), Family, Government.
Someone suggested to me police using excessive force is related to the power structure described in the stanford prisoner experiment.
Interesting to look from higher level as you describe.
Don't be fooled by so many of the excessive force conversations though. last year only 10 unarmed black lives were taken by police officers, 5 of which were assaulting police officers. More people have died during the last week of protests. Is excessive force bad? Yes. It is also much less common, is not continuing to happen, and less destructive than what has happened in these riots.
