Outside custodial interrogation, what mechanism can compel testimony while protecting the witness from self-incrimination?

• A. Subpoena
• B. Immunity
• C. Grand jury
• D. Warrant

Answer: (B)

Granting immunity is the mechanism that allows a witness to testify when there’s a risk of self-incrimination. By offering immunity, the government promises not to use the compelled testimony or any evidence derived from it to prosecute the witness for the offenses related to that testimony. That protection removes the worry of self-incrimination, so the witness can be compelled to speak even outside custodial interrogation. There are two common forms: use-immunity, which bars use of the testimony and its fruits in prosecution, and transactional immunity, which bars prosecution for offenses related to the compelled matter. The key idea is that the safeguard against self-incrimination is what makes the compelled testimony permissible. A subpoena is a tool to force appearance and testimony, but it doesn’t by itself protect a witness from self-incrimination. A grand jury is the body that can hear testimony and issue subpoenas; the immunity grant is what actually shields the witness, not the grand jury itself. A warrant is not the mechanism for compelling testimony.
