Recent Duke Lacrosse situation

I am a lacrosse player, and am obviously bias towards lacrosse programs all over the nation. In the Duke lacrosse case that occurred over the last two years; how would journalists react when the found out that everything they had written and heard was false? Would they just publish the new information? Would they apologize to the people wronged? Would the criticize the people who lied? And what would they do to admit that they published wrong information?

Interview problem?

Is it ok to interview/report on a story dealing with a group that consists of numerous people who I am friends with, even though I have nothing to do with that particular group?

Interviews

When you get info. from a person from an email is it still considered an interview?

Quote Question

When writing a follow up story is it ok to use an exact quote in the new story that you used in the old one?
