How, exactly? It's not like I can use wide-area instrumentation to locate you via your genome. You can imagine how to do it with cameras and faces, but I just don't see the method for DNA.
Imagine the BLM protests (since that will probably be popular with the HN crowd).
There’s video footage of a guy in a mask spitting on the ground after throwing a rock. He’s wearing a mask.
His second cousin did 23 and me.
Actually, statistically many of his second cousins did 23 and me.
Therefore we know who he is.
If only one second cousin did 23 and me, we’ve narrowed the suspects to, perhaps, a few hundred. Filter by apparent height, gender and you have a very narrow set of suspects.
