Final answer:
Defendant's statements made during the crime can be admitted as contemporaneous declarations but must align with procedural safeguards established by the Miranda v. Arizona decision to protect against self-incrimination.
Step-by-step explanation:
Statements the defendant made during the time the crime was committed can indeed be admitted as contemporaneous declarations. This is typically true because such statements are made in the context and excitement of the event and may be considered exceptions to the hearsay rule.
Nevertheless, the U.S. Supreme Court's decision in Miranda v. Arizona established that prosecutors cannot use statements obtained from custodial interrogation unless procedural safeguards against self-incrimination are demonstrated.
This includes the suspect being informed of their right to remain silent and to have counsel present during interrogations, as outlined in Miranda rights. Therefore, the admissibility of statements depends on the circumstances under which they were made and whether the defendant's rights were upheld during their interaction with law enforcement officials.
