Joyner proposes one way to limit gun violence:
One intriguing possibility is mandating some technological solution to make it harder for people other than the registered owner to fire the gun. Various “smart gun” technologies exist or are in the works which rely on RFID chips and biometric devices; cruder devices, which rely on complicated rings to activate the trigger, have been available for decades. If effectively implemented, they could conceivably greatly reduce the number of crimes committed with stolen weapons, including cases such as this one where a teenager steals a weapon from a parent. They’d also, presumably, cut down on gun suicides and accidental shooting deaths of children.
