Let's have our public officials' bodyguards test these for 10 years. Also, ATF and IRS could be required to carry these weapons so that bad guys could not take them away and use against them.
I wonder if they work with a bandaid on your finger? What if you have to fire it with your other hand? What if your partner (in case of LEOs) must use your gun? What if your wife (for citizens) or teenage children need your weapon for defense in the home? Will there be devices that turn these guns off from a distance? Will the bad guys get these devices? Will the govt use these devices against citizens in order to sieze weapons? If you disable the "smart gun" technology, will it be a felony, like converting a gun to full auto or grinding off a serial number? Will "dumb guns" become illegal to possess shortly after the availability of "smart guns".
Well, I think smart guns are a dumb idea.
