Like I said, it proves the person who left it was there, it does not prove that no one else was there.So... If the victim says there was only a single bad guy AND the rape-kit captures an unquestionably adequate DNA sample that could have only been left by the as yet unidentified bad guy AND that DNA fully excludes me as a suspect -- you maintain that the DNA comparison does NOT prove I am innocent (or "not guilty" if you prefer)?
Given that simple, unfortunately rather common example, do you still maintain that DNA can not prove innocence?
Absolutely, DNA cannot prove innocence. perhaps the victim didnt see the 2nd perp, and for that matter, it is IMPOSSIBLE to prove a negative.
