What are we trying to manufacture reality?  The DA at the time did not prosecute because she could not prove beyond a reasonable doubt.  According to American law and tradition that means he is innocent.  No ifs, thens, or buts.  Remember "innocent until proven guilty?"  So now the DA abandons American criminal tradition and says the charges were true, i.e. the dude was guilty even though she couldn't prove it?  Contradiction.  What we think does not matter until we can prove it.
