Cosby is not innocent. He is a liar. He raped women and used drugs to do it.
When he testified in his civil trial as part of his agreement with attorneys to avoid criminal trial, that was only relevant to prosecution for crimes against Cossand. It was NOT blanket immunity from ANY crimes. No attorney should ever be able to give such immunity. It is tantamount to absolution and would allow for future criminal activity.
He stated publicly the following- "Thank you to all my fans, supporters and friends who stood by me through this ordeal. I have never changed my stance nor my story. I have always maintained my innocence."
His criminal conviction should be reinstated by an upper court, though it won't, because he has perjured himself by even pleading his innocence in court. He admitted to doing this to many women in a court filing. It is a public fact, which he is now saying in effect "is a lie."
His legal team has accepted that he may be perjury himself and violating the plea deal in the civil case, in order to free him from his prison term. However, if he spoke one word publicly of his "blanket innocence" before the criminal trial, during his criminal trial, or afterward, he vacated the plea deal of the civil trial himself. If he kept silent throughout, he still vacated it by the statement he made in 2021 above.
