How to Challenge a Video Expert’s Credentials, Qualifications, and Methodology

Evidence in civil and criminal trials includes audio, video, and digital images, where the interpretation of the evidence often becomes a matter of expert opinion.

When opposing counsel discloses or otherwise presents expert testimony or reports on video evidence, inquire into the expert’s qualifications and get the help of a video forensic expert to determine if their statements are based on widely accepted methodology with a scientific foundation.

Video experts often generate non-scientific opinions based on observation and subjective methodology. First, ask whether the expert’s education and training enable them to make certain determinations. Then look at the expert’s experience in applying what they know.
