Why RDI theorist totally deny the significance of the touch DNA on JBR is beyond me.

Then let me help explain it, JuneBug. It's because the science of Touch DNA is the fulfillment (or at least, the beginning of fulfillment) of a prediction made several years ago by LE experts who understand the drawbacks of the science. Some of them even spoke about it in regard to this case in particular.
Specifically, no less than Henry Lee stated a few years ago that in HALF (read that again!
HALF) of all cases where DNA is discovered, the DNA is irrelevant to the crime. Now, that was back in the halcyon days when you actually needed a SIZEABLE sample of DNA in order to do an analysis in the first place.
Flash forward to 2006, during the JMK debacle, an FBI criminologist was interviewed by Bill O'Reilly. During that interview, she expressed a concern that is being taken up by others now: that as DNA testing methods get more sensitive, the MORE likely they are to detect DNA which is not relevant to the crime at hand. One must remember: as good as these machines get, they are still machines. They cannot tell what DNA is relevant and which is not.
Now triangulate that with this simple fact: human DNA is EVERYWHERE. The world is bristling with it. Each one of us is very likely COVERED with DNA which is not our own. Touch DNA does not require a sizeable sample, but as little as two or three skin cells, which could come from anywhere.
I'll be perfectly honest with you guys: if the DNA in question was something unmistakable, like blood or semen, I never would have my awakening, as such. But the idea of a test that can pick up DNA from a single skin cell
scares the living CR** outta me. For now, I can only take solace in the idea that most LE agents, unlike the Boulder DA, are still wise enough to understand the limitations of forensic science and use it properly. But how long will that last?
