In the book Code Of Honor

The LEAST LIKELY reason that the author has decided to tell the story from Kamran's point of view is that it helps the reader...

develop a sense of closeness to Darius even though he isn’t a present character in the story.

become acquainted with Darius through Kamran and can make-up their mind if they think he is a terrorist or not.

discover that there will be a plot twist, and the main conflict will involve in Kamran - not Darius.

witness first-hand how the accusations about Darius are impacting Kamran.

The least likely reason for the author to tell the story from Kamran's point of view is to witness first-hand how the accusations about Darius are impacting Kamran. This is because if the story is told from Kamran's perspective, it is more likely for the reader to understand and empathize with Kamran himself rather than focusing on how the accusations are impacting him.
