There is zero chance of that. You do not need a warrant to test DNA that is left at a crime scene, and the FBI merely violated the terms of service of two genealogy websites. It's completely legal for them to have done that, and the judge made no secret that he was skeptical of the defense arguments here. I honestly don't think that could have possibly gone any worse for them.
This is no different than what has been done in hundreds of murder cases now.
DNA laws are a budding area. What you call a “website”, IRL is “a major commercial company of international location”.
When registering on such sites, one signs an agreement. All of it was less organized in the past. But even “DNA inheritance” will eventually be regulated. Ownership of information will be entered into wills.
From the standpoint of “genetic genealogy”, there is a term “guardianship of DNA”. So I have no question about swabbing any DNA from that party house. The question is, where these DNA s are legally viewed as “guardianship” by the Feds, and where, not.
Here is an interesting issue. When Anne Taylor asked about two other male DNAs found at the house, she was answered that they were not found in CODIS.
So next question would be, why can’t the relatives be searched for them at the same sites that they used to look for BK’s “DNA relatives”? Otherwise, it puts BK in an unfair situation, doesn’t it?
This is a huge problem. Not the DNA, but the “guardianship” of all swabs ought to have been defined the same, “equal”, way.
The judge at BK’s process has said something along the lines of, customers who make DNA open for relationship comparison, why should they care if someone compares them with the suspect? MOO - the answer can’t be that nonchalant. The judge may have not heard about a recent hack into a major commercial DNA site. After that, the answer is, no, some customers would 100% object, IMHO, to any random comparisons.
The customers pay to a company of choice for regulation of DNA storage, processing and collection of their genetic data. Monthly maintenance of trees is expensive. From time to time, one gets messages from unknown relatives with additional information (this is what one pays for, theoretically, chance of getting new information. ) These “website” as you call it is a paid DNA meetup, where only relatives are invited. Unless someone opts in for other kinds of comparison.
Nowadays it is becoming a huge issue. I foresee that in the future it all will be regulated way more strictly.
