I think you should hand your DNA over to the authorities now, mags.

While I'm sure you and your close family are innocent of any crime/protest/mistake in the last 50 years, it would be good to know for certain, I guess.
Perhaps you better run it past them first as DNA is shared data really.

And your children and grandchildren will also be pleased to know that they can be more easily identified for a breach of any future extreme law made perhaps by a federal european government.

DNA matching is a brilliant technique for solving serious crime but it is being abused by the authorities. Worrying.
