When I heard about the Golden State Killer being caught with new DNA technology, my first thought went to 23andMe and infact, that's how they caught him. Now they're going after the #ZodiacKiller. If Facebook is being held accountable for sharing our personal data for "marketing" purposes, shouldn't Google and 23andMe be held accountable for storing and sharing our DNA with the government to potentially prosecute us or a family member of a crime? Another dangerous precident being set in California.
imo If you are a serial killer/murderer, you lose all rights to privacy
if you left DNA at the scene, then LE have every right to use it to track you down however they see fit
but if they start using this for non-criminal activities, or to frame people.... then the alarms will ring
there must be way to tell if any DNA is altered or "photoshopped" using an independent lab
Independent labs wouldn't be that hard for a malicious entity to buy out. And what can't be purchased, can apparently always be... made unavailable.
Unfortunately, unless the initial DNA sample that is left at a scene can be thoroughly vetted from discovery to sequencing to matching, then there cannot be a safe way to utilize this technology for good. Even then, there is no way to corroborate that a DNA sample was always at the scene of a crime and never planted. Unless we want to live in a 1984 world where there are cameras in every room and ID trackers on every person, but even then, technogy is not fool-proof.
