Which of the following is NOT a type of secured bond?

A witness bond is not considered a type of secured bond because it is not intended to secure the presence of a defendant in court through collateral. Instead, a witness bond is a commitment by a witness, assuring that they will appear in court when required. The purpose of secured bonds, such as cash appearance bonds, property bonds, and surety bonds, is to provide a guarantee to the court that an individual will appear for their scheduled court dates, typically secured by a monetary value or collateral.

Secured bonds require collateral, which can be cash, property, or a surety from an insurance company, ensuring a financial stake that compels the individual to comply with court obligations. In contrast, a witness bond does not involve such financial guarantees or collateral aimed at securing the appearance of the witness; thus, it does not fit the category of secured bonds.
