Not suprised. Also not suprised they have been handing this data over to law enforcement for years now. Its no just to track down people whove taken said test but also people who are related even distantly. The fbi estimates they can use dna evidance to single dowm the possible people to 2 or 3 out of the entiriry of the us

i am not sure what you mean by this sentence, but you probably misunderstood something.
dna doesn’t single down anything, as in it would help you track something. it tells you if two genetic profiles are a match (that means they come from same person), or that they are genetically similar and how distant they are - that tells you that the profiles come from x times removed relatives. after that, it is down to normal police work.
here is veritasium video about how they used this technology to find and convict the infamous golden state killer - piped.video/watch?v=KT18KJouHWg

Yeah and with a big enough database u can get an almost perfect modal of the country and everyones placw in it.

with big enough database you simple have every single person in it. that still doesn’t back up the quote i disputed in any way.

They caught the Bay Area Strangler(or whatever his title was) by finding a dna relative match on one of these services and using that to narrow down suspects. DNA can absolutely be used to narrow things down without just having a direct 1:1 match saying it’s THAT person.
