DEEPFAKES IN INTERROGATIONS.

In recent years, academics, policymakers, and others have sounded the alarm over police use of artificial intelligence in areas such as predictive policing, gunshot detection, and facial recognition. One area not receiving attention is the interrogation of suspects. This Article addresses that gap, focusing on the inevitable coming use by police of AI-generated deepfakes to secure confessions, such as by creating and presenting to suspects a highly realistic still photo or video falsely indicating their presence at a crime scene, or an equally convincing audio recording of an associate or witness implicating them in a crime. That police should resort to trickery to secure a confession is nothing new. Indeed, in Frazier v. Cupp (1969), the Supreme Court condoned a police lie to a suspect that an associate implicated him in a crime, holding that the deceit did not violate due process because it did not render the confession secured involuntary, while positing that an innocent individual would not falsely confess. Building upon the now-recognized reality that innocents do indeed confess and research demonstrating the coercive impact of police use of the "false evidence ploy" (FEP) in securing confessions, scholars have urged a general ban on its use. Courts, while often expressing dismay over police resort to FEPs, typically conclude that they do not violate due process, but at times have held otherwise, expressing particular concern over police presentation of fabricated physical evidence to suspects (as opposed to orally relating its existence, as in Frazier). While sympathetic to a ban on police deceit in interrogations more generally, this Article singles out deepfakes for specific concern, based on their unprecedented verisimilitude, the demonstrated inability of the lay public to identify their falsity (despite confidence to the contrary), and the common belief that police are not permitted to lie about evidence, much less fabricate it. Ultimately, the Article makes the case for reconsideration of Frazier, based on research findings of the past fifty years, as well as the many major changes to the criminal legal system since 1969, especially the significantly increased pressure felt by defendants to plead guilty (very often on the basis of confessions, rendering them more susceptible to FEPs). A ban on deepfakes will also have important functional benefits. These include providing ex ante guidance to police, who lack clarity on the parameters of permissible interrogation techniques, and judges, who must decide motions to suppress based on application of the notoriously indeterminate due process voluntariness standard. More broadly, a ban will act as a partial yet important bulwark against the deleterious wave of disinformation now sowing distrust in governmental actors and institutions. If deepfakes are condoned in interrogations, it is not hard to imagine that judges, jurors, witnesses, and members of the public will be skeptical of the reliability of evidence in criminal cases, undermining a cornerstone of the nation's constitutional democracy. The Article concludes with a discussion of how a ban can be achieved and why ameliorative tweaks to the current framework regulating confessions are not up to the challenge of checking the formidable threats posed by police use of deepfakes in interrogations.
