Kendra Kowalski was indicted on theft charges and questioned by agents without counsel present. She signed a form with buried waiver language and made incriminating statements. At trial the prosecution could not introduce the statements in its case-in-chief. The statements remained available to impeach Kendra if she testified because the court found the statements voluntary and the waiver knowing and intelligent.
Kyle Knight faced arraignment while his competence was questioned. The court placed the burden on Kyle to prove incompetence.

No. Prior consultation does not eliminate the need for a knowing and intelligent waiver at the time of the interview. The focus remains on whether the defendant understood the rights and voluntarily relinquished them during the specific proceeding.
…a statement which contained a typed-in clause stating that he had "full knowledge" of his "legal rights" does not approach the knowing and intelligent waiver required to relinquish constitutional rights. Cf. Haynes v. Washington , 373 U. S. 503, 512-513 (1963); Haley v. Ohio , 332 U. S. 596, 601 (1948) (opinion of MR. JUSTICE DOUGLAS). No.…

…not required by the Constitution) could explain the Court's inclusion of a right to counsel and the requirement that it, too, be knowingly and intelligently waived.

Courts assess the totality of the circumstances including whether the defendant received clear notice of the right to counsel, any encouragement from officers to proceed without counsel, and the presence or absence of a specific written waiver. Professional background alone does not substitute for a clear and uncoerced choice.
