So what does the judge say about this 'clear' evidence of contamination?
A skeptic should be able to evaluate logic and evidence directly, instead of deferring to a judge, priest or shaman.
If the DNA profile of a suspect on a piece of evidence is proof the suspect was involved in a crime, why don't the DNA profiles of unknown persons also prove they were involved in the crime?
If the DNA from unknown persons is present due to factors unrelated to the crime, shouldn't this also be possible for the the DNA of the suspect?
