My dad was witness to a professional hit in the 60s.

He was in a popular bar for drinks on a Friday night. It was the local watering hole for a bunch of factories and such in a major city. There were often more than a hundred people there after work.

A man of average height, with brown eyes, brown hair, wearing a brown suit (lots of people were in suits) asks a guy at a table: ”Are you John Smith?"

The man responds that he is Jon Smith.

Mr Average takes a revolver out of his pocket and shoots John Smith four times and leaves through the front door. No one tried to stop him.

The room went silent at the first shot. There were more than a dozen witnesses with a clear view.

Welcome to 1960s Chicago.
