A firearm should be simple and reliable with an absolute minimum number of failure points. Of course this law doesn't apply to Law Enforcement firearms. LE personnel would never permit a requirement to have this "safeguard" in their weapons. After all what if they are wearing gloves, have dirty hands, adjust their grip away from the reader, need to use their partner's weapon, etc. These same issues would come up for civilian users; but no one wants to admit it. Assuming this technology will even work and can be bought at a reasonable cost who will be responsible to ensure that LE has "safe" weapons? Not the authors of this law. Now consider the case of an owner who wishes to teach his children to shoot or allow his friend to target shoot with his firearm. How will they be added (or subtracted) from the memory of the firearm once it is "imprinted" with its owner? If it is a simple process that anyone can download the software off the Internet; what did this accomplish? The roster of unsafe, impractical, bad, and openly dangerous implications of this law is extensive. If this is a good idea LE should carry them as well.

Awesome! Now when crime comes calling, you can just say "please wait, I have to log-in to my gun!" Seriously? This is such an anti-gun fantasy. Also, the picture shows so much - finger on the trigger tells me this person does NOT know the rules of handling a firearm.

H and K have had these type of handguns available for years, the cost of these firearms is enormous. I agree that this safety measure will decrease the unwanted violence whether intentional or not.
