 What happened with Bill Cosby? What happened with Weinstein in those trials? Prosecutors zealously tried to get at all of this extraneous evidence to prove their case, and all it ended up doing was gift-wrapping issues on appeal that caused the case to be overturned. The conviction had to go back down. In Cosby's case, the conviction was vacated with prejudice, no retrial. But now everybody in Weinstein's got to go through it all over again.
