The hysteria does not overturn the evidence. But the fact that two separate juries couldnt convict should say something though. Maybe the doctors testimony would have changed the verdict. Who knows? Maybe the allegations were true but thats just one case out of many. In fact there are still people in jail from other convictions.So unless the hysteria overturns actual physical evidence, then the evidence stands and there was child abuse.
Except they didnt. The McMartin trials both ended in hung juries and Presidio was only dropped because under Californias hearsay laws neither the Doctors nor the Parents could testify about the childrens(who being so young were unfit to testify) first hand accounts. Which is a loophole that is closed in most other states.
