United States v. Apfelbaum

The Fifth Amendment guarantees the right to be free from compulsory self-incrimination. It permits an individual to refuse to answer questions; but it does not give him the right to answer falsely.


This carries over to the Garrity warning, in that once a governmental employee is given immunity, they must be truthful. Furthermore, any false statement made during the interview can be grounds for prosecution for giving a false statement. In fairness, discussion of truthfulness would be suggested in training with line officers. An officer should be aware of the pitfalls of giving statements to internal affairs and the consequences of their actions should they not adhere to the law.
