I don't know that I would go that far in an OTU setting.
I would think that it is much like the modern AED (Automatic External Defibrillators). They can diagnose and recommend a shock, but a person still has to push the button to get a shock. It also has the failsafes so that if you press the button when a shock is not recommended, it won't shock.
So, I figure a smart gun can do everything to help you right up to actually pulling the trigger, which still has to be done by a person.
