Ah, that's simple to explain. He's white.
When go to/from/thru the airport, if I was with Hebrew speaking Jewish co-workers, everything would get thru in a few seconds.
There was one time I (Asian) was with Indian co-workers without the company issue security letter, we were search for 3 hours at the airport. Both of our laptop were completely disassembled and Xray multiple times. We were questioned for a long time separately by multiple people.
They must have our previous trip history base on passport record, etc. But ...
Anyway, later I asked a Jewish co-worker about is there any law in Israel about anti-discrimination base on race, color of skin, language spoken, etc. He said we always / must discriminated base on those info!
A different way for thinking compare the "official PC" view of US.
