Why can't Toronto Sun cannot present Warminton's "opinion" on Dattani as "news"

If indeed Mr. Warmington wanted to act like a real journalist, or if he believed what his said in his piece, that, “It is important that he [Dattani] get a full and fair hearing on this because no one wants to see someone tarnished on bad information,” he might have bothered to talk to Dattani himself, or quote from the CBC article that was published on Dattani the day before, where Dattani responds to all the criticisms leveled at him.
