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.

[HenryBemis]

Well they can narrow it down to the family, unless it was the very DNA giver that left that DNA sample on the scene of the crime.

And since 23andme (as I assume others) don't do these anonymously, there is no hope. Unless people use someone as a proxy (i.e. I-1 give my sample to a male colleague to send it as his-2, he-2 gives his sample to someone else to send it as his-3, and so on..). Police would eventually find the guilty in case of a crime, but the 23andme's of this world will be selling confusing (wrong) data.

[stef25]

There are plenty of cases where DNA is found at the crime scene, run through a database, match is found with a relative. Then the cops start looking at the family and boom there's your shady uncle with priors they got their guy.

[quickthrower2]

Yes it has come up a few times on forensic files usually on cold cases.

[dylan604]

If this was someone trying to fly under the radar by using this scheme to buy burner phones or some such, sure. But this is literal DNA, so even in your attempts to obfuscate, they’d know the name and the sample do not line up, but then be able to link the sample to a family and then figure out who you really are

[pavel_lishin]

They can narrow it down to individual family members, based on how much DNA overlap there is.

[pfdietz]

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.

[mschuster91]

> I can help track down distant family members who have committed crimes? Sounds like a plus.

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].

[pfdietz]

It's precious that you imagine not getting your DNA sequenced will provide any sort of shield against dystopian governments.

This sort of thing looks more like a psychological crutch than an actual effective action.

[dylan604]

That’s not what the comment was driving at. At all. It’s about how data you think is innocent can be used in a manner you never thought about nor intended for dark purposes.

[mschuster91]

I actually had intended to point out the dangers of "scope creep". Everyone is happy with a lot of pretty invasive stuff - dragnet surveillance, targeted surveillance (i.e. bugs placed in a suspect's home/car/computer/phone), DNA and fingerprint mass tests, no-knock raids - in severe crime cases such as terrorism, murder, rape, child sexual exploitation or abduction. So far, so good, and almost all Western countries have such provisions for decades that were introduced under the premise "it's only going to be used for <prior list of severe crimes>".

But in recent years, the scope of said "severe" crimes list has expanded massively, across the Western world, driven by both powerful industry lobbies (such as the copyright cartels) and "concerned citizens" aka authoritarians in disguise... and now you got a DNA investigation for about 4.000€ in damages of broken glass and a ticketing ATM. No matter what: this scope creep is not justifiable.

On top of that comes the risk of "what if our governments and the tools/data they and society (both in the form of individuals and companies) possess fall into the hands of authoritarians". For a long time this risk has been laughed off, but nowadays both the far-right (in Europe and the US) and the far-left (in Southern America) have seriously raised the probability of such a scenario.

[mistrial9]

> Everyone is happy with a lot of pretty invasive stuff

could you stop repeating this simple fallacy? Because millions of people could not organize and opt-out of something being commercialized, that also benefits government, in the USA Does Not Equal "everyone is happy"

in fact, lots of people are deeply unhappy.. so the statement "everyone is happy" is not only not true, but actively provoking.

It is not in the power of an unhappy or protesting individual citizen, let along an elderly, impoverished or medically vulnerable person, to stop the rollout of Big Tech Thing.

[pfdietz]

Why is DNA investigation supposed to be limited to "severe" crimes? It's just another investigative tool. The idea that it should be limited implies there's something sordid about it. Why should I accept that implication?

An amusing thing here is that the arguments against DNA were also made against the use of photography, back in the 1800s. At some point people have to realize that personal unease is not an argument.

[dylan604]

> Everyone is happy with a lot of pretty invasive stuff

I beg to differ. The fact we're even having this discussion means not everyone is happy with the situation. Maybe Stockholm Syndrome has kicked in for you, but I'm still resisting

[pfdietz]

Fair. On the other hand, I'm a bit surprised that anti-immigrant forces in the US haven't made DNA sampling compulsory for new immigrants. The argument would be these would be harder to track down by these techniques, because the ancestry information is not as available, giving them an "unfair" advantage over white Americans.

[kasey_junk]

The US does do DNA collection for anyone it detains whether they end up being granted legal status or not.

They were processing so much DNA that they had to write a special rule allowing border agents to _not_ collect it if it would cause operational difficulties to do so.

[peyton]

I don’t think that fits with how people on this side of the pond think about immigration.

[pavel_lishin]

Your father submits his DNA to 23 and Me.

One of your brothers committed a crime.

The police, during an investigation, find your father's data and realize that one of his children is the criminal.

Congratulations! You are now the target of an investigation, the purpose of which may not be to find the truth, but to successfully convict a suspect.

[anonymouskimmer]

> You are now the target of an investigation

All you have to do to clear your name for that crime is to turn over your DNA to the police to be in their records forever[1], and Bob's [2] your brother [3].

[1] - You might be able to get a court to order that your DNA records are destroyed after proving your innocence, but it's an ask to believe this would actually happen in every case.

Why do you make this issue gendered, and if you do why would it impact only men father of illegitimate children, and not cheating mothers ?

[watwut]

Cause in the case of cheating mother, it is clear she is the mother. And to confirm fatherhood of husband or partner, no external registry is needed or helpful.

[pfdietz]

The mother will already be connected to the child. The father is what would be needing tracking down.

I mean, wasn't that completely obvious?
