as already said, there is pretty limited use for thise, as most, if not all, rounds will have likely have multiple prints on the, and prints on a case also do not mean you were the one to fire the gun, just that you touched that round at some point. Only real use I see is if there is a crime, and the cops have NO leads whatsoever, which menas they have 5 billion suspects, they can pull all the prints of a case, and use that list of people whose prints could be identified (not everyone has prints on file somewhere), as a short list of people to at least start looking into. Still likely to get a dead end the majority of the time, but once in a while, it will lead them to the right person, then they just have to make a case, and get it to stick.
If it solves 1 out of 1 million murders that would otherwise be unsolved, then good on them.Thats better than nothing. also, this doesnt really hurt gun rights in any way I can see (they could already pull prints they old way, examine rifling marks on the bullet, and marks on the case, so this is just an extension of that), and as said, MAYBE this will pan out, and will quell some of the screeching for microsatmping, ammo registartion, etc.Doubt it, but who knows. Depends on how well this noew thing works, and how well they can sell it as accurate, reliable, and effective.
