Ballistic identification is the science of using a ballistic fingerprint to identify the specific firearm used in a shooting. A comprehensive ballistic identification system would connect a bullet or cartridge case recovered at a crime scene directly to the make, model and serial number of the gun from which that bullet or cartridge case was fired. In effect, comprehensive ballistic identification would allow police to trace a gun even before they recover that gun.
