Final answer:
False, Officers must stop questioning only if a suspect unambiguously requests an attorney; ambiguous requests do not mandate an immediate cessation of questioning.
Step-by-step explanation:
The statement that 'officers must stop questioning immediately if a suspect makes an ambiguous request to have an attorney present during questioning' is false.
According to the Supreme Court decision in Berghuis v. Thompkins, a suspect must invoke their right to remain silent unambiguously.
If the request for an attorney is not made clearly and unambiguously, police officers are not necessarily required to stop questioning.
In the landmark case of Miranda v. Arizona, the Court mandated that suspects must be informed of their rights, including the right to counsel, and that questioning must cease if they clearly assert their right to not speak or to have an attorney present.
