Find What Matters in Police Evidence

Defensa analyzes body-worn camera footage and custodial interviews to identify Miranda violations, extract timelines, and surface defense-relevant issues — saving you hours of manual review.

Evidence review shouldn't take longer than the trial

Criminal defense attorneys face an overwhelming volume of video evidence. Body-worn cameras, dashboard cameras, and custodial interviews can amount to dozens of hours per case — all requiring careful review for procedural violations and defense opportunities.

  • Hours spent watching footage that yields minutes of relevant material
  • Miranda warnings buried in chaotic arrest scenes
  • Timeline inconsistencies scattered across multiple recordings
  • Contradictions between officer statements and video evidence
