So people were asked if they give permission?
From the line: "rejected a request for their DNA samples to be used in a research project", you can quickly assume that all those who's profiles were involved had given permission.
But then there would be no point in this article. So I'm assuming that ONLY THE COPPERS were asked if they give permission. Everyone else is included automatically, innocent or not, children included. Can that be true?
Sounds like it.
Just the same as any coppers caught on speed cameras are asked to explain why, before mostly being let off when they supply the default "It's Police Business" answer.
Us ordinary folks just get busted. No explanations asked for. No explanations accepted. Pay your fine or we'll make it a much bigger one, should you choose to waste our time trying to defend your innocence.
Chalk up another loss for the people. Add it to the list.
@ El Reg: Can we please get a Nazi icon for these stories?
