Craig Peyer isn’t the only CHP cop killer — there have been several in Southern California alone. The Golden State killer was a former cop.
The connection is simple. Some people with a badge and gun seek to prey on others, not protect or help them. They select weaker or vulnerable people.
Some are sexually motivated like Craig Peyer. They select young female victims who have their desired appearance.
Others are racially motivated and select people of different races. They can be assured, as Peyer was, that they will be protected and if they do the crime then they can get away with it, sometimes forever.
It is misuse of authority and occurs in almost every line of work.
It is also the same with those who commit crimes during wartime. Means, motive, opportunity, reason to believe they will neither be caught nor punished.
I’m sorry this is difficult for you to understand. Mr. Peyer was not an isolated instance. There is someone who would like to do this in every organization like the CHP. He was by no means an “isolated instance.”
