<p>A computer-controlled laser etching probe (30) etches a firearm-identifying indicia such as a barcode encoded serial number into the bore of a firearm (32). Owner registration data coupled with the serial number is stored in a central database (48). A computer-controlled scanner reads the barcode from a bullet fired from an etched firearm for comparison with registration data in the central database, thereby identifying the registered owner of the firearm from which the bullet was fired.</p> |
