I'm not sure that's exactly what happened, based on this report. There was apparently no immunity deal and no plea agreement, just a public statement by the DA.
If I were in Cosby's position back then I would have invoked the 5th Amendment and refused to testify in the civil case.
Right and he still admitted under oath that he gave quaaludes to women and then raped them.
It was not an immunity deal, it was a plea deal. The original DA did not have enough evidence to charge Cosby criminally.
So, the DA said: tell us what happened and we will not charge you criminally, but we will allow the civil case to proceed.
So Cosby testified and the civil case proceeded.
A new DA used Cosby’s testimony to charge him criminally.
That is violating the original agreement.
Actually his attorney prolly advised given the peculiarity of the civil process over lack of criminal pursuit that he be candid and pay the money
And get immunity
Which ultimately he did....did not work out ....perfectly...3 years in jail and prison
Better than the 20 he deserved
candy is dandy,
but liquor is quicker.
