Argument: Compelling a criminal suspect to disclose a passcode is testimony privileged by the Fifth Amendment. The Fifth Amendment prohibits compelled disclosure of the contents of a suspect’s mind. Compelled disclosure of the passcode is testimonial. The Fifth District properly declined to apply the foregone-conclusion rationale in this case. The Foregone-conclusion analysis applies only to the production of specified, preexisting business records. Even if the foregone-conclusion rationale could apply in this context, the state must describe with reasonable particularity the incriminating files it seeks. Law enforcement has alternative methods of accessing encrypted devices.
