Defamation in journalism involves false statements that harm someone's reputation. Libel refers to written defamation, while slander is spoken. Understanding these concepts is crucial for journalists to report ethically and avoid legal issues. Key elements of defamation include falsity, publication, and harm to reputation. Defenses against claims include truth, opinion, and privilege. Journalists must verify information, use accurate quotes, and promptly correct errors to avoid defamation lawsuits.
