It’s a thing, and has been since the late 90’s (I think). Reliability is the main issue. The first one I had heard of had mechanical reliability problems If I remember correctly.
Haven’t looked at Biofires products lately, but they weren’t really weatherproof last I heard and weren’t recommended for duty use as a result. And then there is the eye watering sticker price. A Taurus PT92 is less than half the price of the Biofire, and has a track record for good reliability.
I seem to remember a state, New Jersey, I think, had a law on the books saying that if multiple manufacturers came out with biometricly locked firearms that biometric locks would then become mandatory. As for if that would help things, probably not.
US centric, violent crime is down. Not the lowest it’s been currently, but better than it was when I was growing up.
