Should police be allowed to search commercial genealogy databases to solve crimes without a warrant?

Investigative genetic genealogy exploded into the public eye in 2018 when police used it to catch the notorious Golden State Killer by uploading crime scene DNA to consumer genealogy sites. It works by finding distant relatives of a suspect and building a family tree to narrow down the culprit, a technique that has since solved hundreds of cold cases. However, this creates a massive loophole in digital privacy, as millions of people who never took a DNA test are now identifiable through their relatives' data. Proponents argue this is a revolutionary forensic tool that takes violent predators off the streets and exonerates the innocent. Opponents argue it bypasses the Fourth Amendment's protection against unreasonable searches and paves the way for a dystopian genetic surveillance state.
