Earlier quoted context omitted.
FYI, the police is able to find criminals now by finding DNA sequences similarities with your relatives. Not saying this is good or bad, I am just saying you don't know the extent of the impact to your personal freedom when your relative's DNA is shared.
I can help track down distant family members who have committed crimes? Sounds like a plus. I think the angst about this comes from men who don't want their status as fathers of illegitimate children (or, rapists when they were younger) unmasked.
It's no longer so easy when the definition of "crime" gets expanded. Let's take this scenario:
- you're a first generation Chinese immigrant in the US
- a nephew of yours is in China and critical of the CCP
- you decide to have your genome scanned into 23andme or whatever to determine if you are at risk of genetic illness
- your nephew sprays an anti-CCP tag on a wall somewhere
- the Chinese police gathers DNA evidence from a laxly discarded spray can, but doesn't have fingerprints so they can't immediately link the can to your nephew
- the Chinese government, either via a legal subpoena or via espionage, gets its hands on your genetic profile from the genetic analytics company
- the Chinese government finds your data, now knows that the sprayer must be related to you in some way, and forces everyone of your family to subject to a DNA test
Sounds dystopic? Yes. But this is exactly where we will be headed. Police here in Germany already do DNA tests on petty vandalism [1].
