Yup. The FBI maintains NICS. It's a national registry for guns and explosives/materials. Guns are required by law to be registered. I can sit in my cruiser and look up for instance your name/SS# and pull all of the fire arms registered to your name, and your permits. I can also pull up a fire arm's serial number and back trace it that way if a paper trail has been left. All guns have a serial number from the factory, which the factory registers who they sold it to (ex. Dick's Sporting Goods) who then registers who they sold it to (the customer).

Registering firearms doesn't prevent criminals from getting guns.
