I've been wondering if any agency in the US government has been using DNA databases to do "genetic triangulation"--and if not, when they'll start.
I'm in 23andme, and I get messages saying "someone who is your 4th/5th/6th cousin wants to connect" all the time. I figure if I was given a bit of DNA from a crime scene, by cross-referencing all of the 4th,5th, and 6th cousins, the number of potential people matching that DNA has got to be tiny.
Science fiction dystopias used to hypothesize a complete DNA database but I'm pretty sure even the spotty coverage we have now is pretty powerful.
