Paper this Sunday am had an interesting article on DNA, privacy and the Californication serial killer. As the data bases grow and more and more connect the familial dots happen;think of the legal implications.
(1) All the girls who get pregnant can (or perhaps as a condition for child support HAVE to submit a DNA sample of them and their child) which the law can then trace back to the guy. Then, without trial, he can be made to provide up to half his income as child support.
(2) DNA at a robbery scene collected is "proved" to be yours, yet you were not at that store at that time, but the day before but can't prove it.
(3) and from another article, the real humans unmixed with Neaderthal DNA come from southern Africa; so the white supremacist are arguing Neaderthal is better than human. Gotta love the life.
