How is fabricated digital evidence challenged in Georgia criminal defense?
Concerns about fabricated or manipulated digital evidence have grown as technology has advanced, and challenging such evidence in a Georgia case involves examining its authenticity and integrity. Establishing that digital material is genuine is central to its use.
Authentication is the foundational hurdle. Digital material does not come into evidence on its own; the side offering it must first show that it genuinely is what it is claimed to be, and doubts about where it came from or whether it has been tampered with go straight to that showing. Alteration, outright fabrication, and selective editing are all live concerns, and the burden of establishing genuineness rests with the party relying on the material.
Technical examination can be relevant. Digital material can sometimes be analyzed for signs of manipulation, such as inconsistencies in metadata or other indicators, and such examination can support a challenge. The integrity of the material is examined through these means, since indicators such as inconsistent metadata or signs of editing can call its authenticity into question.
The chain of handling matters. How digital evidence was collected, stored, and handled can bear on whether it remained unaltered, so gaps or irregularities in that handling can be significant. The reliability of the process used to preserve the evidence is relevant here.
A challenge to suspected fabrication tends to press on three fronts at once: the authentication showing, any technical fingerprints of manipulation, and the soundness of the chain through which the material was preserved. Weakness at any of those points can keep manufactured or doctored material out of a trial.
