Dutch Police Ask 8000+ Citizens To Provide Their DNA
sciencewatcher writes "In an attempt to solve a rape and murder of a 16-year-old girl, the Dutch police have asked 8080 men to provide their DNA. All these people lived 5 km or less from the crime scene at the time of the murder. This reopened cold case is the first large-scale attempt not to hunt the rapist and killer but to locate his close or distant male relatives. All data gathered will be destroyed after the match with this particular murder. There seems to be great public support for this attempt." Shades of The Blooding.
It's clearly for the children.
That is what this boils down to. There is no "right" answer, but citizens of each country answer the question diferently.
"We'll destroy the DNA afterwards, we PROMISE...."
I don't generally like the idea of giving DNA samples to anyone. However, if the authorities are very direct and up-front about it, and provide me with a signed statement that the records will be destroyed after each sample is "cleared", then I'd do it in this case.
I'll always trust the entity who asks for something over the entity which does the same thing in secret without permission.
Even so, I sincerely doubt that this will lead to the perpetrator, for obvious reasons.
This is a good article on the problems with fishing expeditions like this. Basically, the farther you cast the net, the greater the chance of false positives. What's worse, if there's just one false positive, it becomes next to impossible to argue your innocence because people look at the improbability of a single person being a false positive instead of the probability that there are false positives.

I read this "All data gathered will be destroyed after the match with this particular murder" and immediately think bullshit.
As a rule, once they have this, it never seem to go away.
I would never submit to this unless I was required to -- this is a fishing expedition. Anybody who submits is probably innocent, and anybody who refuses is going to be treated as if they're guilty with something to hide.
Yes, this is terrible. But asking everyone to submit exclusionary DNA because they've ran out of places to look ... well, I find that to be a really scary precedent.
The next step of course would be to just simply have everyone's DNA on file just in case they ever needed it.
