What sort of privacy do you loose tho?

Have you seen Gattaca? Any DNA data held by the state will eventually be held by private enterprise.

I get the point. But terrible example. Gattaca allowed a scumbag to endanger a billion-dollar space mission to further their own ego. Not the poster child for privacy.

Did you miss the entire sub plot about an underclass?

No. Yet the 'hero' was patently unfit for the job they sought, and cheated other qualified candidates to get it. At a possible societal cost in the billions.

It might have been a good movie, had the protagonist been actually qualified for the job but cheated of the opportunity because they were the underclass. That would have played into the theme instead of refuting it.

I am baffled by the reputation Gattica has received.

But opposite is true now - state is getting data from private enterprise.

Yes I watched Gattaca not really long ago, based on some HN or Twitter FUD. Pretty stupid movie.

I honestly thought the whole genetic aspect was completely beside the point. The people in the movie just trusted the black box algorithm. Nobody gives a damn whether it even works or if all the results are manipulated or simply inaccurate.

Is preventing the next rape/murder not worth it?

Given that people shed plenty of blood for our liberties, no, preventing all rapes/murder is not worth surrendering all our liberties.

I.e. I'm not willing to trade away all my liberty for security. A certain level of background crime is acceptable. Just like I accept a certain level of risk every time I get in a car, eat a steak, go jogging, etc.

No, it is not worth it, and in the long-run may not have the desired effect.

For me, after seeing this, I would possibly not report being raped. Arresting the rapist isn't going to directly help me (depending on the situation), so by selfish game theory I shouldn't risk compromising my DNA

Using a rape victim's DNA from her rape kit without consent etc is much more likely to promote rape than to prevent it.

Its a letter of the law versus spirit of the law. I am of the later. Investigating one crime does not inherently give permission to use data from that crime to start trying to solve other crimes unless they are directly connected, i.e. tying a bunch of murders together with similarities because it may be a serial killer instead of one off murders.

I fail to see the preventative aspect. The system really isn't set up for that.

By indexing rape victims DNA?
