That's journalism, my friend. People in privileged positions always get interviewed in stories. At the very least, it's the journalist's job to interview those people. NOT interviewing Erol would be considered a serious deficiency in the story.
But what do you expect? Who would you interview that knows MLSE inside and out and would speak against them? And even if you did, you'd still need Erol's quote in "defense." That's objectivity.
