Metal Storm
The National Institute of Justice (NIJ) is exploring a unique application of biometrics technologies: a handgun that can recognize its owner and only fire when being held by that person. This innovation could make it impossible for a criminal to steal an officer's firearm and use it against other people. Metal Storm, the company that is working with the NIJ to develop the gun, has presentations and technology descriptions on its home page.
