Civilian vs. Expert

In the reading, it is prescribed that a reporter should only give the facts (no opinions) of a story and then the reader can interpret those facts as he sees fit. However, what about the role of source opinions in the paper, do they or should they have a spot? An expert surely has a role, as he/she has the first hand experience that could be deemed factual, but what about a mere civilian onlooker who has an opinion on some event or situation? I believe that it is the reporters duty to decide what should go into a story and what should stay out, but I believe that more often than not, the civilian voice should be left out and the discussion should be left to the experts. What do you think?
