He was just a patrol officer, I think. I read a puff piece about him several years ago, which described his training at the police academy in Honolulu. In spite of his years of police experience, he still had to go through the training like any other recruit. And they said he would graduate and be like any other rookie policeman.
HAHA! Then he wasn’t invited to be chief. The vast majority of chiefs are political hacks of the general casey sort. They frequently float around from agency to agency as chief, kissing the a$$ of their political masters and generally making their cops miserable and pissed off.
