Taken separately, the leggings DNA, the underwear DNA, and yes the fingernail DNA may not be significant due to their degraded state. Taken together, where each sample of DNA matches the other, is HUGELY significant. It no longer matters if the DNA is degraded, as long as it matches.

Thats why the latest thing we've got out of an official body and the media is the 'intruder DNA' and how 'the Ramseys should be treated as victims and not suspects.'
Its time to get with the times if anyone is really, truely interested in a solution. The evidence tells us that the solution is with an intruder scenario.
You forget: the case is in different hands now.
