Yes, DNA science does advance and yes,of couse it would be a good thing to finally clear up the murder of Rachel Nickell. Just one small quibble?
The tests, part of a 13-year reinvestigation into Nickell’s murder, are said to show a one-in-five-million chance that the DNA did not belong to Napper.
Is that what they actually mean? For I\’m not sure how that can actually be calculated. Don\’t they mean that only one in 5 million have that DNA? Thus that there are in fact 10 people in the country with it?
