I was really shocked today when my grandpa showed me his new .22 caliber 1911 look alike pistol. It was a cool gun but was shocked me was a small envelope that came with the gun that had the shell from the first bullet that was fired from the gun when he ordered it before picking it up at the store. The writing on the envelope described the make and model of his fire arm and gave notice that the state had on file the matching bullet for his pistol. I live in Washington and my grandpa said it was some kind of new law. I guess in the future all of our weapons will be IDed on a database including the picture of what the bullets will look like coming out of your guns. Sounds like gun-control policy is inching it's way up...

Its a good way to frame someone with a stolen gun..but most criminals are not that smart to do something like that anyway.
A 2006 study by the University of Southampton in England asked six veteran fingerprint examiners to study prints taken from actual criminal cases. The experts were not told that they had previously examined the same prints. The researchers' goal was to determine if contextual information—for example, some prints included a notation that the suspect had already confessed—would affect the results. But the experiment revealed a far more serious problem: The analyses of fingerprint examiners were often inconsistent regardless of context. Only two of the six experts reached the same conclusions on second examination as they had on the first.
Ballistics has similar flaws. A subsection of tool-mark analysis, ballistics matching is predicated on the theory that when a bullet is fired, unique marks are left on the slug by the barrel of the gun. Consequently, two bullets fired from the same gun should bear the identical marks. Yet there are no accepted standards for what constitutes a match between bullets.
