In terms of the RS' DNA "profile" on MK's bra clasp, I have a few questions. And if anyone with any expertise can explain it to my limited understanding I would appreciate it.
I am not a scientific person, and I won't pretend to be one on the internet. My question is excluding the contamination factor, is it a "full" profile? I don't really understand the discussion of alleles and stutter. My understanding is that it can rule out certain people like Amanda Knox and Casey Anthony. However, is there a European DNA profile that would exclude most people that were born and perhaps have multiple generations of ancestors from North America compared to someone that was European? Is it something like the old school days of pre-1990's when the attacker had O+ it didn't really mean too much since approximately 1 in 4 to 1 in 2 had that blood type. However, if it was AB- or B- it was very incriminating since that was closer to a 1 in a 100 chance.
Also with the way Stefanoni did the test with the machine set at testing limits the machine was not designed to perform is it akin to one of those music graphs that show the treble, bass, etc. that may be able to assign a piece of music is heavy metal or rule out bossa nova, but it can't ascertain between Led Zeppelin, Black Sabbath, or Anthrax?
If this makes no sense I appologize, I am just trying to understand what it means as an extremely ignorant layman.
