I disagree. If there is DNA collected that shows that someone ELSE committed the crime in question, then that is definitive proof that the suspect did not commit the crime.
In fact, *I* committed the crime we are talking about -- whichever one that is.
I done 'em all.
I thought the DNA question was only that it did not prove the "STATES" case.
In most cases it did not show another person was guilty.(?)
One piece of evidence "out of place" after all this time and "reasonable doubt" arrises and re-trying the case is not possible.
Maybe I did it! Not you. Were we together? LOL
