Why do I really care about other people with similar genetics to me?
This seems to be a greater risk for me, if I put myself into that database.
And if someone else has a similar genetic as mine, and they commit a crime, then I’m automatically roped in as well. Do I really want the police knocking down my door, and slamming me to the ground, while they barge into my house with assault rifles and ballistic protection gear, and pointing their guns at every member of my family. This is a case of mistaken identity. But their m.o. is to shoot first, and ask questions later. No thanks!
This is the Law of Unintended Consequences at play here.
And for all the talk about cross linking your genome with others to find markers to get clues on how to cure diseases, well, I never really bought into that.
It may help, but I really don’t care. The disease problem will need to be solved in another way, that doesn’t involve the compromise of my security, however remote it may be.
