DA is really mostly a politician.... depending on public perception a DA may file charges that they can't win merely to show the public a desire to do something about a case. However, the public stances in this case seem to not be that strong overall in one direction.... I've a feeling based on the controversial element of the case, the lack of a chance to win, and the unlikelihood of the action been a boon to constituency views; that the DA will not ultimately file charges.
