Excerpts taken from: Area inventors' idea would match bullets to guns and gun buyers By RICK MONTGOMERY The Kansas City Star Just about everything is bar-coded these days. So why not bullets? It is a question framed in the simplest terms by a pair of area inventors. Diagrams filed with the U.S. Patent Office depict the technology in two stages. The first stage, incorporating a machine about the size of a home furnace, would rely on a computer-controlled laser to etch an individual bar code inside a gun's barrel. The second stage involves scanning that code after it has been grooved down the side of a fired bullet. Investigators would use a central database to match codes, 'thereby identifying the registered owner of the firearm from which the bullet was fired,' according to the patent issued Oct. 8.
