I know I'm not a serial rapist &/or murderer. I hope my family members are not. The question is: what do I value more? A society without serial rapist killers or my family? I guess I prefer a society without that sort of nonsense, so even if my DNA is used to ensnare a relative, and they were doing horrible stuff, I'd be heartbroken that a family member had gone so astray but grateful they were unable to hurt anybody else. See the investigative work using shirttail relative DNA to isolate the Golden State Killer. That said, do I want law enforcement to have willy nilly access to DNA to, for example, chase down littering? No, IMO that is an inappropriate level of intrusion for the societal problem. Do I trust government to exercise good sense with these tools? I fear not so much. But I guess we will get used to the intrusions just as we have become accustom to the gov hoovering up all our communications metadata to find terrorists.
