Ethical Sports Dilemma

I was reading my monthly Glamour magazine when I came across an interesting little snippet. The woman who exposed Alex Rodriguez's use of steroids came back to visit him in a locker room where she asked him a question and he responded coldly to her. She explains that it was her job and duty to report his use of steroids and that the public deserved to know, apparently he didn't see it that way. Was she intruding on his personal life or was she warning baseball fans about a baseball player's abuse of drugs?
