The Ketchum Report (Continued)

Plussed Mulder.

Good read Mulder, thanks

The article gave her way too much credit. But don't take the article's word that there was contamination, it's in the sequences she provided. I think it's pretty clear who's seeing what they want to see.

I think you're overstating the expertise of forensic DNA experts. They specialize in looking at two samples and computing the probability of a match, not at sequencing novel genomes. I think Timmer's article did a rather good job of explaining why Ketchum was a poor choice for the study.

 

TWO different labs independently made the SAME repeated errors in procedure resulting in improper analysis of "contaminated" samples?

I find that very hard to believe.

 

I finally read through the whole thing, and it reads like an exercise in circular reasoning and selective application of standards.

 

On the one hand, the author acknowledges the validity of forensic dna testing and the expertise of forensic dna analyists.  Their practices, after all, are time-tested and court approved.  Yet here comes a novel dna sequence and suddenly those time-tested, court-approved methods are complete bunk?  And the analysts who previously were said to be very good at spotting and eliminating contamination are mysteriously incompetent?  TWO LABS worth of analysts?

 

That doesn't pass the "sniff test".

Apples and oranges. Forensic DNA testing is a whole different world from sequencing novel genomes.

The equine genome was novel until the the equine genome project sequenced it, which Ketchum participated in.

[Guest]

Was proof of that published in a made-up Journal too ?
