DNA is where technology renders the idea of privacy and ownership moot... If a few people related to me share their data 23andMe has more than enough to convict me of a crime or predict my health to some degree. My DNA is not just mine, but it's really shared property. We really have few social conventions or intuitions to cover this situation (I think).
