I must admit that I know the Kohli family personally because they belong to Ferozepore, my hometown. Parduman, a very jolly fellow grew up with my late brother and then they lived in London together before the Kohlis moved to Glasgow. His younger brother Charanjeet and I grew up together and went to the same school although he was 3 years my senior. They are one wonderful bunch.

Glasgow had become one of the most racist cities in the 70's because of the explosion of the Muslim population, mainly from Pakistan, and due to the industrial base there, where hardworking Asians were taking over the jobs from the natives. Edinburgh was more mellow.
All of us with turbans were also used to be called Pakis in the UK, which was used as a slur.
In fact, Raj came and stayed with me in Los Angeles during his hitchhiking tour of the Americas in the late 80's. He did not wear a turban then. I am glad to see him back with the turban. A handsome Copper!
