From the article: > By contrast, safety features on firearms—such as smartguns unlocked by an owner’s thumbprint or a radio-frequency encryption—are opposed by the National Rifle Association, whose allies in Congress also block funding for the sort of public-health research that might show, in even clearer detail, the cost of America’s love affair with guns. Can someone explain the NRA to me? At this point they come…
No implementation of a TouchID-like system for guns would be perfect and so the gun owner must weigh the potential benefits and risks. I don't think the NRA's members want to take that choice away from the gun owner, but even having a commercial solution come to market means some states will require it's use. IIRC one state has laws on the books to mandate the use of the technology once it's commercially available.
