 Bullet and gun analysis is another forensic discipline that has been identified in recent studies as being less scientifically reliable than thought.The Bureau established an interdisciplinary commission in 2013 to establish the highest scientific standards in forensic testing and to understand the limits of these tests, and how they may be properly used in court.With a heightened attention to scientific rigor in its forensic testing, the FBI lab in 2005 abandoned its four-decade-long practice of tracing bullets to a specific manufacturer’s batch through chemical analysis, after its method were scientifically debunked.
