Dad was a patrolman NYPD. From the mid 40s till the late 60s. He chose NOT to advance because of more corruption the higher you go.
He was happy to take his pension and go. He was a good cop. Though Im sure he probably took a corned beef sandwich from a local shop keeper on occasion. They were happy to have cops look in on their businesses.
It was a different time
The scum rises to the top - and the top sets the leftist policy.
