Absolutely, DNA cannot prove innocence. perhaps the victim didnt see the 2nd perp, and for that matter, it is IMPOSSIBLE to prove a negative.
perhaps the victim didnt see the 2nd perpOh my goodness! With "flailing logic" that desperate, you are either a shyster lawyer, or you are cut from the same cloth!
DNA proves innocence on such a regular basis, that it is not even arguable! If there is only a single perpetrator, and ONLY COULD HAVE BEEN a single perpetrator, and the DNA is clearly a mis-match, then innocence is proven beyond all reasonable doubt and it *cannot* lie. That sort of case is *THE* most common criminal investigation resolved by DNA comparison. Period. It is as assured as arguing the sky is blue or the grass is green!
Stubborn adherence to such an obvious falsehood is *comical*. That I was so easily able to get you to publicly demonstrate it is hilarious! Enjoy that fantasy world you've constructed around you...
