DNA of relative indicts man, cuckolding ignored

Slashdot pointed to this story of a man indicted via his *relative's* DNA sample: http://news.bbc.co.uk/2/hi/uk_news/wales/3044282.stm But an interesting, unmentioned issue is this: in population DNA surveys you find that a lot of purported fathers *aren't*. So the possibility of indicting a cuckolded man on the basis of nominal (only) relatives is quite real. [list rel: tech DBs, errors, law, biosurveillance]
