@Unseen. My last laptop had a fingerprint scan mechanism which substitutes as a password. I wonder how hard it would be to transpose that mechanism onto a gun trigger. It was really easy to add other people’s fingerprints when there was need, and just as easy to delete them.
I’d be surprised if someone hasn’t already started work on something like that. The problem probably has to do with building it into the gun without adding much to the bulk.
