Proper gun storage and family education avoids almost all those problems. The only ones it doesn't are ones like Lanza where the kid is disturbed in the head, but still theoretically competent enough to bypass standard protective measures.On the other hand Deck, a lot of terrible incidents of gun violence in the US comes down not to criminal activity, but guns misused by non-owner citizens (ie kids and family of gun owners). In these incidents, a smart gun would be a big preventative measure-- I think that's unfoubtful. So, if the weapon can be used to effectively work for it's intended user, society stands to see more peace just from preventing those incidents.
Meanwhile, having to making guns dumb is just one more barrier to would be criminals. I'd have to say the overall effect seems heavily weighed to greater social safety.
And what happens when 13 year old miss (or the wife) is the only one home when someone breaks in. She can't use dad/hubby's "smart gun" because it's not bio-coded for her - or can they bio-code multiple users or tag guns to multiple bracelets.? Can you take the bracelet off while you sleep? Where does it have to be stored? Can you trust your kids not to lose their gun bracelets?
I'd rather we avoid the impulse to pass intrusive laws and mandates when the issue can be addressed by product users not being lazy and inattentive. The gun cannot be un-invented, all these "smart" guns would do under such mandate is price more responsible people out of the market for home defense and provide an additional layer of potential failure when seconds count.
I also don't think it's wise, just based on how guns actually work, to put sensitive machinery into an object that will inherently receive frequent amounts of high stress. The function of the gun's mechanism is to redistribute the force of the explosion to the projectile, but as everyone knows guns still have recoil. It's physically impossible to distribute all of that energy into the projectile - some of it does get forced back throughout the weapon and its user.
