Makes you really wonder how many privacy laws that DNA test company violated.
Maybe the relative gave permission to match to others or for "research purposes"?
Thing that is creepy here is that data is used with some other information for purposes that are more nefarious than just solving crimes or identifying unidentified corpses. Like identifying sperm donors or digging out information about cheating whores spawning cuckold babies. Might potentially lead to more than little family drama. At some point it might become a tool of extra legal political or other suppression. Maybe even target selection tool for genocide. Who knows.
I think there's a lot more at stake with this stupidity than just identification criminals or missing people.
