The idea behind the carefully curated release is to change the narrative. So now we get photos of celebs/and Clinton, who are presumably not involved in the sex trafficking activities around Epstein. By the time incriminating photos/evidence of Trump or Republicans are released, people will have become accustomed to the innocent narrative - yes X,Y,Z's in a photo but they're innocent.
That will be EXACTLY what the DoJ/Trump's admin want people to keep on thinking when believable evidence against Trump, lands.
