This only encourages me. My DNA is on record in various places, and if any relative of mine commits a crime I want the honor of being the person who fucked them and sent them to prison. I would tout the event as an esteemed accomplishment.
Everyone seems to be worried about a sci-fi movie where clones are made from cheek swabs or corporations use DNA to deny certain services.
The former is a pipe dream and the latter is already (partially) illegal in the US via the Genetic Information Nondiscrimination Act of 2008.
If evilmegacorp is going to break the law today then they'll break it tomorrow as well.
Every conceivable scenario in which DNA can be used to harm an individual can be answered with "well a bad actor can already do that today using different methods".
As far as I'm concerned a database of DNA is no different than a database of mugshots or fingerprints.
Mugshots and fingerprints have both led to false-positives being reported.
"Oh but DNA might lead to a false-positive so it must never be used" differs little from "eyewitness testimony, mugshots, fingerprint analysis, confessions, and every single investigative technique ever used in the history of humanity has unassailably led to false positives therefore they should all be banned".
