I think that as soon as these "smart guns" are ready to market, our politicians should set a proper example for the rest of us, by equiping their bodyguards, capitol security, etc, with these guns. After all, it is for the children.
It is obvious that police are the most in need of smart gun technology, after all, some criminal or the thousands of terrorists flooding the country might take their guns away from them and use them on us. So, they need to have smart guns.
And our military should have all smart guns, so that the military cannot turn against the government. The guns could be programmed and controlled from afar, by people who have our best interests at heart.
