What is the test for indicating that a suspect wants an attorney?

"sufficiently clearly that a reasonable police officer in the circumstances would understand the statement to be a request for an attorney." (Davis v. United States (1994) 512 U.S. 452, 459.) When a suspect makes an ambiguous or equivocal statement, or makes no statement after admonishment, it is often good police practice for the interviewing officers to clarify whether or not she wants an attorney. (Id. at p. 461.) The police are not required to end the interrogation. (Berghuis, supra, 560 U.S. 370 [130 S.Ct. at p. 2260].)
