Miranda Defenses: Which of the following is a Miranda defense?

• A. Knowing and Intelligent Waiver
• B. Coerced Confession
• C. Impeachment
• D. Public Safety Question

Answer: (A)

The essential idea here is that Miranda warnings only lead to admissible statements if the suspect willingly and knowingly waives their rights. A knowing and intelligent waiver means the person understood the rights, understood the consequences of waiving them, and chose to speak despite that understanding. When the waiver isn’t knowing and intelligent—due to confusion, language barriers, youth, mental impairment, or coercive pressure—the resulting statements are typically suppressible. That’s why this option fits a Miranda defense best: it focuses on the validity of the waiver itself.

Coerced confession touches on voluntariness, which can affect admissibility, but it isn’t the specific Miranda defense being tested here. Impeachment concerns using prior statements to attack credibility, not whether a Miranda waiver was valid. The public safety exception is an exception to the warning requirement, not a defense to the admissibility of a Miranda waiver.
