| Thats what I mean....the accuracy is fairly low...I think I read somewhere that it was about 60% accurate. Many guns don't have rifled barrels, making one comparison impossible. Other times when they want to match the case to the firing pin requires that they find the spent casing, also not easy most of the time. Couple that with the 90% of crimes where the weapon isn't there, and you have very VERY rare instances where it can even be done.
My point was relying on this practice to help alleviate any form of gun violence problem isn't feasible.
