QROT-27: How the latest variant is "proven"? By noting the way it does NOT pass the test for something ELSE, then assuming all those non-matches are the same thing!!
That is, a MISMATCH, plus a giant, non-scientific, assumption is how the latest variant is "identified."
If the DNA for a suspect doesn't match, then you merely have evidence to exclude that person. Scientifically, this is no better than assuming a NON-match to one person in DNA results PROVES that another person did it!!
