Antonio Regalado Twitter thread on genetic genealogy, DNA privacy, and total DNA de-anonymity
I used to know some technicians in the NYC Medical Examiner's lab. They had all been DNA typed (to detect accidental contamination). So, their little society was a picture of what is to come, of total DNA transparency.

They would do stuff like find out who stuck gum under the table. Also, who was peeing on the toilet seat in the bathroom.

So There’s a second technology at play: environmental DNA sampling. Once police get a name they tail the suspect and try to get some DNA he leaves behind. To make the match to crime scene sample. Police have gotten DNA from:
- a car door handle
- a straw
- a paper napkin

Imagine storm troopers of a repressive regime descending on a meeting place of the resistance. Just swab the whole place and find out who was there from DNA left behind.
Technically, total DNA de-anonymity is possible. Far as I know there’s no law, no protection, against identifying you from your DNA.

In crime cases, [this is] being done by “amateur” using a database (GEDmatch) that itself is highly informal.

DNA Doe Project
"The DNA Doe Project was founded in 2017 by Colleen Fitzpatrick and Margaret Press. The Miami County Jane Doe case was accepted as one of the first cases for the project. The DNA Doe Project relies on genetic genealogy tools similar to those used by genealogists for analyzing DNA results normally provided by direct-to-consumer testing companies. (..) We have been fortunate to find many of her DNA matches through the database GEDmatch. Belle's DNA matches appear to be mainly people in the tri-state area including Cabell County, WV & surrounding regions. We are in search of people who are from the aforementioned regions and who have used commercial DNA services such as Ancestry, FTDNA, or 23&Me. We hope that these people might consider downloading their raw DNA data and uploading it to GEDmatch (free). A DNA database is only as strong as the amount of users included, and although we have many excellent matches to Belle, there is strength in numbers!"

The brave new world of genetic genealogy - MIT Technology Review
The combination of DNA and genealogy is a potentially a huge force for good in the world, but it must be used responsibly. In all cases where public databases like GEDmatch are used, the potential for good must be balanced against the potential for harm. In cases involving adoptee searches, missing persons, and unidentified bodies, the potential for good usually markedly outweighs the potential for harm.

But the situation is not so clear-cut when it comes to the use of the methodology to identify suspects in rape and murder cases. The potential for harm is much higher under these circumstances, because of the risk of misuse, misapplication or misinterpretation of the data leading to wrongful identification of suspects. The stakes are too high for the GEDmatch database to be used by the police without oversight by a court of law. 

However, we are not looking at a dystopian future. In the long run the public sharing of DNA data, when done responsibly, is likely to have huge benefits for society. If a criminal can be caught not by his own DNA but through a match with one of his cousins he will be less likely to commit a crime in the first place. With the move to whole genome sequencing in forensic cases in the future, it will be possible to make better use of genetic genealogy methods and databases to identify missing people, the remains of soldiers from World War One and World War Two as well as more recent wars, and casualties from natural and manmade disasters. We will be able to give many more unidentified people the dignity of their identity in death. But we each control our own DNA and we should all be able to decide what, if anything, we wish to share.
