ProvaLens — Practice Area Guide

AI Document Review Guide for
Criminal Defense Attorneys

How to find Brady material, timeline contradictions, and discovery gaps before the prosecution counts on you missing them.

Applies to: Felony and serious misdemeanor defense — high-volume discovery cases Updated: 2026
Discovery in criminal cases arrives in bulk, often close to deadlines, sometimes incomplete. ProvaLens indexes every document against a timeline and cross-references officer statements, bodycam transcripts, and lab reports, flagging possible contradictions automatically for review.
1
Discovery Completeness
  • All documents referenced in police report accounted for ProvaLens reads the police report and extracts every reference to supplemental reports, attachments, and evidence items — then cross-references against what was actually produced. ProvaLens automates this
  • Lab reports indexed and chain of custody verified All forensic lab reports are identified, indexed by evidence item, and the chain of custody documentation is cross-referenced for completeness and any gaps in custody transfers.
  • Bodycam footage listed vs. footage actually produced Body-worn camera footage referenced in the police report and officer statements is compared against the media index in the discovery production — flagging any footage described but not produced. Common Brady issue
  • Witness list cross-referenced against statements produced Every witness named in the police report and supplemental reports is identified, and the discovery index is checked to confirm statements were produced for each named witness.
2
Officer Statement Analysis
  • Initial report compared against supplemental reports for inconsistencies ProvaLens compares the original incident report against every supplemental report by the same officer — flagging changes in the account of events, times, or descriptions between reports. ProvaLens automates this
  • Deposition or grand jury testimony compared against police report When an officer testifies at a grand jury or deposition, their testimony is cross-referenced against the written report — any factual difference is flagged with citations to both documents.
  • Bodycam transcript vs. written report discrepancies flagged The officer's written narrative is compared against what the bodycam audio and transcript actually captured — highlighting any discrepancy between the documented account and the recorded reality. High impeachment value
  • Multiple officer accounts cross-referenced When multiple officers filed reports on the same incident, their accounts are compared against each other — flagging possible discrepancies in the sequence of events, positions, or observations.
3
Timeline Reconstruction
  • Chronological event timeline built from all sources Every timestamped document — CAD dispatch logs, bodycam metadata, arrest records, booking reports, and officer notes — is combined into a single chronological timeline. ProvaLens automates this
  • Gaps in official timeline identified Periods where the official record has no documented activity — particularly around the time of the alleged crime or arrest — are flagged for investigation and cross-referenced against other sources.
  • Alibi evidence mapped against prosecution timeline Alibi documentation — receipts, security footage records, phone records, witness accounts — is mapped onto the prosecution's timeline to identify corroboration points and gaps.
  • Cell tower and GPS data cross-referenced against stated locations When cell tower records, GPS data, or location-based evidence is produced, ProvaLens maps those data points against the prosecution's timeline narrative and the defendant's stated location. Technical evidence cross-check

Brady / Giglio Compliance
  • Prior misconduct references flagged for Giglio analysis Any reference to an officer's prior discipline, internal investigations, or credibility findings in the produced documents is extracted and flagged for Giglio impeachment analysis. Brady / Giglio material
  • Inconsistent statements by witnesses identified Witness statements that conflict with each other, or that changed between the initial statement and later accounts, are surfaced automatically with citations to the specific documents.
  • Exculpatory evidence indexed and summarized Every document or statement that contains potentially exculpatory information — however buried — is identified, indexed, and summarized in a dedicated Brady materials report. ProvaLens automates this
  • Lab analyst prior testimony cross-referenced If prior testimony by the lab analyst is available, ProvaLens cross-references their testimony in this case against prior cases — flagging any inconsistencies in methodology or conclusions.
From the field: In one case, ProvaLens cross-referenced three officer supplemental reports against the original incident report and found the suspect's described clothing changed across all four documents — a detail buried in 600 pages of discovery.
