True or false?

Black, a Certified Fraud Examiner (CFE), interviews Green, a fraud suspect. No one else is present at the interview. During the interview, Black accuses Green of committing fraud. Later, it turns out that Green is innocent. Green can sue and recover damages from Black on a claim of defamation if Green can show that Black knowingly made the false statement on an unprivileged occasion and that the statement caused economic harm.
