In the case of Salinas v. Texas, the United States Supreme Judicial Court recently considered the question of whether a defendant’s pre-arrest silence, prior to being placed in custody or receiving Miranda warnings, can be used against him in a subsequent criminal prosecution as evidence of consciousness of guilt.
In this case, prior to being taken into custody, the defendant voluntarily answered some questions from police about a murder. After answering several questions, the defendant remained silent when he was asked whether any ballistic evidence testing would yield matches between his shotgun and the shell casings found at the crime scene. Rather than answer, the defendant remained silent, shuffled his feet, and bit his lip.
After being silent for several moment, he then continued answering other questions from the police.
