Which of the following is NOT a condition of a valid waiver of Miranda rights?

A valid waiver of Miranda rights requires that the individual understand their rights, that the waiver is made voluntarily without coercion, and that the individual is aware of the potential consequences of waiving those rights.

The correct choice indicates that "being under great stress at the time" is NOT a condition for a valid waiver. This is important because legal standards for a Miranda waiver emphasize that while the circumstances surrounding the waiver may be relevant in evaluating whether it was made knowingly and voluntarily, experiencing stress does not in itself invalidate a waiver. A person could still have a clear understanding of their rights and the implications of waiving them even while under stress.

In contrast, knowing and understanding one's rights, having a voluntary intention to waive those rights, and being aware of potential consequences are essential components. If any of these elements are absent, the waiver may be deemed invalid. Thus, being under great stress does not automatically affect the validity of the waiver, highlighting why this choice is correct in identifying the condition that is not required for a valid waiver.
