DNA, re: Ancestry searches. How do police get access?

I started a thread earlier about polygraph and that led me to this question...
The Golden State Killer was captured because a relative did a DNA Ancestry search and the killers DNA matched crime scenes. This process has been used by other law enforcement agencies as well.
If you do an Ancestry search, does it then become public because you give them permission to compare your DNA to others DNA?

Because the case went to higher courts and the courts passed it allowing law enforcement to have access

Read Unmasked by Paul Holes. He explains how they started doing that.

Is that just for this one case or all unsolved cases?
Does law enforcement have to have a court ruling for each individual case?

They don't just go in and start digging around.

They simply upload the dna sample from their suspect and relatives are matched just like they would be if you uploaded your dna yourself.

The Golden State Killer would not have been caught without it. How did they know where to look?
He wasn't a suspect.

Where were you on November 13th between the hours of 3 and 4?

Before officially connecting the Original Night Stalker to the East Area Rapist in 2001, some law-enforcement officials (particularly from the Sacramento County Sheriff's Department) sought to link the Goleta cases as well.[167] The links were primarily due to similarities in modus operandi. One of the already-linked Original Night Stalker double murders occurred in Ventura, 40 miles (64 km) southeast of Goleta; and the remaining murders were committed in Orange County, an additional 90 miles (140 km) southeast. In 2001, several rapes in Contra Costa County believed to have been committed by the East Area Rapist were linked by DNA to the Smith, Harrington, Witthuhn, and Cruz murders. A decade later, DNA evidence indicated that the Domingo–Sanchez murders were also committed by the East Area Rapist (also identified as the Golden State Killer).[2][16][168]
On June 15, 2016, the FBI released further information related to the crimes, including new composite sketches and crime details;[134] a $50,000 reward was also announced.[169] The initiative included a national database to support law enforcement's investigating of the crimes and to handle tips and information.[170] Eventually, "through the use of genetic genealogy searching on GEDmatch, investigators identified distant relatives of DeAngelo—including family members directly related to his great-great-great-great grandfather dating back to the 1800s. Based on this information, investigators built about 25 different family trees. The tree that eventually linked to [DeAngelo] alone contained approximately 1,000 people. Over the course of a few months, investigators used other clues like age, sex, and place of residence to rule out suspects populating these trees, eliminating suspects one by one until only DeAngelo remained."[16]
Identification of DeAngelo began in December 2017 when officials, led by detective Paul Holes and FBI lawyer Steve Kramer, uploaded the killer's DNA profile from a Ventura County rape kit to the personal genomics website GEDmatch.[171] The website identified ten to twenty people who had the same great-great-great grandparents as the Golden State Killer; a team of five investigators working with genealogist Barbara Rae-Venter used this list to construct a large family tree.[172] From this tree, they established two suspects; one was ruled out by a relative's DNA test, leaving DeAngelo the main suspect.[173]
On April 18 2018, a DNA sample was surreptitiously collected from the door handle of DeAngelo's car;[60] another sample was later collected from a tissue found in DeAngelo's curbside garbage can.[174] Both were matched to samples associated with Golden State Killer crimes.[19] Since DeAngelo's arrest, some commentators have raised concerns about the ethics of the secondary use of personally identifiable information.[175][16]

I suppose you get a court order to allow the submitted sample to be checked, anonymously, against all samples in the database(s).
Database X gives me a call and says "you won't believe it, but we got a match."
I say "cool, don't say anything else."
I write a subpoena (probably a duces tecum) for that record to be presented.
But again, just a dumb former cop.

You don’t need a warrant to search a public database

But in that case, if the database is public then I suppose you wouldn't need one.
People's stupidity knows no bounds I suppose.

It's too late now, buddy.
You better confess before things get worse.

nope, you freely give up your rights to it when you do the ancestry search, read the fine print and the extra fine print in lawyer speak.
they dont spell out they will be giving it to the cops for the asking, but they do say you give them the right to share it with anyone and make it part of their shared database. thats how the whole ancestry thing works, it doesnt work if they dont share it with anyone and everyone

Why? Most people aren’t criminals and would you really care if your DNA on a genealogy site assisted law enforcement in narrowing down a suspect? What exactly is someone going to do with access to your DNA that you feel makes it something so private?

The Golden State killer lived within a mile of my house. His daughter worked in the ER of the hospital I worked at too.

In short, there is no need for my DNA profile to be in any database. Period.
During my LE career one of the states I worked in had an initiative to collect officers' DNA for exclusionary purposes.
If they want it, they can get a court to order it.

I one cousin is on the database. You’re caught.
Posted on 12/28/22 at 5:34 pm to Abraham H Parnassis
But that’s not exactly how it works. Yes you have to trust the company acting as custodian of your DNA records and with GEDmatch that would indeed be an issue, but in general the only way someone is going to use it is someone who has also uploaded their DNA. It’s not like you can go online and browse the results of some 3rd party at will. I understand the hesitancy to an extent but in all honesty I’d be pretty surprised if the vast majority of people’s DNA hasn’t been sequenced already.
