To add on a bit here. New Jersey actually has a regulation in place that once smart guns are seen as viable, they will be the ONLY guns allowed in the state.

Of course cops would love to have smart guns working because then it would increase their safety should a crook steal their weapon - the catch is that it has to work flawlessly, thus why no police force has yet signed off to have any current smart gun tech.
Now for anybody with a modicum of engineering awareness, they realize that a smart gun could never "remain" a smart gun. It would help with preventing an immediate return fire, but if the gun is stolen away, it would be easy for criminals to dismantle it and remove the smart tech. The only way to prevent this would be to go the way of Apple and have guns that cannot be taken apart for basic maintenance - thus reducing them to the realm of the super rich and large organizations.
The problem with Bob and his allies is that they think the gun is like a magic wand - usable only by trained wizards. It's not, it's a bow & arrow with a controlled explosion replacing the string. (In fact, if you mentally replace "bow & arrow" into smart gun debates and proposals, you'll start to get an idea of how silly it all sounds.)
That Bob will sometimes sound off to try and sound knowledgeable about guns ("that kid should be using a scope?") makes the comedy priceless.
