My only reasoning behind registration would be the fact that where the marker was bought. This would aid in the fact that police could track down leads with an address on file. And that would be better than it is now. Just like the supermarkets do with those value cards. There was a story a year or so ago where a drug maker was busted because he bought his supplies at a local Safeway, and he used his value card. He even took the time to fill out and return the registration slip, with his address, phone number, everything needed for police to track him down.

Sometimes stupidity just amazes me with people, lol.

As far as ballistics go, I wouldnt doubt that they can, technology is way more advanced than we realize. CSI is more than just a show.
