Vice President Joe Biden said on Friday that “smart gun” technology might have been able to stop the Sandy Hook Elementary School massacre.
“Vice President Joe Biden says he’s interested in technology that would keep a gun from being fired by anyone other than the person who bought it ,” The Associated Press reported  Friday.
“He says evidence shows such technology may have curtailed what happened last month in Connecticut when 20 youngsters and six teachers were gunned down inside their elementary school,” the AP said.
A gun with the “smart” technology would sense the gun owner’s biometrics and grip pattern, allowing only the registered gun owner to operate the weapon. Similar devices, such as RFID chips  and magnetic rings, are both available and under development.
