But this has nothing to do with Smartgun technology. As you, yourself, point out:
You are somehow missing the point of Smartguns. The data in your cite is mostly about how having gun in the home is more dangerous than not having one because there are more suicides and instances of the owner using the gun against a family member or accidentally shooting someone while cleaning it or handling it irresponsibly. Or where a child gets ahold of the firearm and accidentally shoots himself or sibling.
There is technology available that prevents many of these instances. Gun locks, trigger locks, safes, etc. These would prevent a large number of such accidents. The only thing they wouldn’t prevent are the suicides by the actual owner or the intentional violence against family members. But, of course, Smartguns wouldn’t prevent that either.
The point of Smartgun technology is to prevent an assalaint from gaining control of someone’s firearm during a scuffle and then using that firearm against said someone. This is the only purpose for Smartgun technology that cannot be accomplished with other, simpler methods.
Because the number of instances where a firearm is wrestled away from the victim and then used against him are so low compared to instances where the owner fires it at someone, the failure rate that people are concerned with is the gun failing to fire when needed.
Smartgun technology is not for preventing your child from getting into your guns. Its to prevent the person you are already pulling a gun on from violently removing the gun from your hands and then shooting you with it. It is also to prevent someone from pulling a loaded weapon out of your holster during a scuffle and then turning it on you.
Are these instances so prevalent in society that Smargun technology actually makes any sense? If they do happen often enough to warrant the need for the technology, does the technology exist today to design a practical system that has close to a zero chance of failing to fire when the owner intends to fire it in defense of his/her own life.
