Скачать или смотреть Expert WITNESS CRUMBLES Under Cross-Examination About Bullet Evidence!

This courtroom exchange dives deep into the science behind firearm toolmark analysis and exposes the tension between measurement and interpretation.

The discussion focuses on firing pin impressions, crater measurements, tool marks inside the impression, and how the same firearm using the same ammunition can still produce different sized markings from shot to shot. As the questioning tightens, the limits of magnification, measurement precision, and forensic certainty come into focus.

The back and forth highlights a critical issue for juries and viewers alike. Are examiners measuring the weapon itself or the variable impression it leaves behind. When does scientific explanation turn into assumption. And how much variation is too much when conclusions carry real consequences.

This clip is a textbook example of how technical forensic testimony can become complicated under cross examination and why understanding the difference between manufacturing standards, tool marks, and impressions matters in court.

Watch closely as the questions repeat, objections are raised, and the expert is pressed to clarify what is being measured and what is not.
