Reasoning
Deepfake audio and video evidence have already appeared in U.S. civil and family-court proceedings (e.g., 2023 Colorado family-court case and 2024 New York Surrogate’s Court), while the Department of Justice’s 2024 guidance explicitly flags AI-generated material as an emerging litigation risk; combined with the rapid consumer availability of tools such as ElevenLabs and Runway Gen-3, the probability that a documented criminal-trial incident surfaces before 2028 is high. Structural factors accelerating adoption—mobile-phone recordings now comprise >80 % of evidence in local felony cases and courts lack standardized forensic-AI authentication protocols—further compress the timeline.Key uncertainty
Whether state and federal courts will implement mandatory AI-content authentication rules before 2026, potentially delaying public confirmation of an actual criminal-trial use.
