A bit more specifically, because Cosby was no longer facing criminal charges, he was not eligible to plead the 5th amendment in the under-oath depositions he was required to make on the civil cases, so he didn't and he admitted to giving women quaaludes, etc. If the DA's office had not informed Cosby that they were dropping the criminal charges, Cosby would not have been forced to make those incriminating statements.
