Provide a detailed account of the situation, explaining who was involved and what kind of story was being reported. State why and how you came to be a source, noting the basis of your claims to credibility (such as expertise or insider information). If you provided misleading information, say this plainly and why you did so. Correct the facts.
Take responsibility, recognizing your role in the situation. Acknowledge the hurt caused by your actions. State specifically whether you have damaged the reputations of journalists, members of the community or colleagues. Use language to describe your wrongdoing such as "foolish," "reckless," "selfish" and "cowardly."
State your regret. Promise you will not repeat the offense and that you will work to repair the damage. Ask for forgiveness from the news organization, your employers and anyone else harmed by your actions.
