The chapter defines defamation, slander and libel: their similarities and differences. There are also distinctions made between criminal and civil libel. We explain the burden of proof in a libel suit, and what must be shown by plaintiffs or defendants. Public figures have a harder time winning libel suits than private figures, and the rationale is provided. Media reporting someone else’s libelous statement aren’t immune from libel suits. Republishing libel is still libel. Truth is an absolute defense in a libel suit, but often difficult to prove. Media have many other possible defenses in libel suits.
