The most important element in this Witchita case, that people who use all arrests like this as an excuse to discredit women who report being raped will overlook, is that the rapes he was arrested for are real. The alleged victims in those 2 stranger rape cases are not the ones responsible for his arrest.
He was arrested 3 days before the DNA lab results showed that his DNA didn't match the DNA from the 2 rape victims. This is clearly a case that goes beyond not having credible evidence that he is the rapist, the DNA mismatch provides credible evidence that he is in fact innocent of 2 serious and real crimes.
The real rapist is still at large.
