When Brad Bannon was preparing to defend David Evans (one of the Duke lacrosse three), he read John Butler's textbook on DNA profiling. His cross examination of Dr. Brian Meehan was one of the pivotal moments of the case. For the newest edition of his textbook Dr. Butler asked Mr. Bannon some questions, including his common tactics in challenging DNA evidence. Mr. Bannon replied in part, "Did the lab follow acceptable standards of DNA analysis? Did it follow its own protocols? Is the lab applying those standards and protocols consistently or selectively? For example, why do you call a peak below 150 RFU as a true allele for one purpose, or in one case, but not for another? If there are such internal inconsistencies, do they usually inure to the benefit of one side's theory of the case? If so, is that evidence of bias?"
For me one of the earliest clues of bias in this case was the fact that Stefanoni accepted peaks below 50 RFU as part of the profile associated with the knife. Inman and Rudin discussed the need for a cutoff that is set before one starts the experiment.
MichaelB,
Do you think that 176 and 177 were not taken from Filomena's room?
