ballistic fingerprinting

Ballistic fingerprinting is a method used to identify firearms based on unique tool marks left on bullets and cartridge cases when a gun is fired. Each firearm produces distinctive markings due to minor imperfections and wear in its barrel and components. Forensic experts analyze these markings using specialized microscopes and software to match bullets or casings found at crime scenes to a specific gun. This technique helps investigators link a weapon to unsolved crimes, much like a fingerprint links a person to a crime scene, providing valuable evidence in criminal investigations.
