Using AI to Review Discovery in Criminal Cases

What "Discovery" Is

Discovery is the evidence the prosecution must share with the defense — and in a real case it can be overwhelming in volume. The defense has a duty to review it carefully, because the case can turn on a single detail hidden inside it. The challenge is not usually a lack of evidence; it is finding the meaningful pieces in time. (See our page on criminal discovery.)

Where AI Helps in Discovery Review

• Indexing and organization. Sorting thousands of pages and hours of media into a searchable, structured form so nothing is overlooked.
• Timeline building. Pulling timestamps and events from many sources into one coherent sequence — useful for testing whether the state's narrative holds together.
• Body-camera and recordings. Helping a lawyer work through long video and audio efficiently to find the moments that matter. (See our page on AI, bodycam evidence, and strategy.)
• Cross-referencing statements. Comparing witness statements, officer reports, and prior accounts to flag contradictions.
• Issue spotting. Surfacing potential suppression issues, procedural problems, and gaps for the lawyer to evaluate.

A Concrete Example

Suppose three officers wrote reports, a squad camera and two body cameras recorded the scene, and there are dispatch logs and a handful of witness statements. The decisive fact might be that one officer's report places an event at a time the video contradicts, or that a statement shifts between two tellings. Reviewing all of that by hand is slow and error-prone. AI can help align these sources so the lawyer can see — and then independently verify — where the accounts diverge.

The Non-Negotiable: Attorney Verification

AI-assisted review is a starting point, not a conclusion. Anything the tools surface — a flagged inconsistency, a timeline, a suggested issue — is checked against the actual record by the attorney before it is relied on. The lawyer decides what matters, what is accurate, and how to use it. The tool accelerates the search; the lawyer makes the judgments. (See our page on why human judgment still matters.)

Confidentiality and Care

Client information is sensitive, and using technology responsibly means handling it with appropriate safeguards and confidentiality in mind. Done carelessly, technology creates risk; done carefully, it produces a more thorough review without compromising the client's protections.

Why It Matters for Your Case

A more complete discovery review means fewer missed details — which can be the difference between a contested issue that goes unnoticed and one that becomes a motion to suppress, a cross-examination point, or leverage in negotiation. The aim is simple: make sure nothing important in the evidence slips by.

Key Terms
