That may have been the pretext but none of what the prosecutor said could possibly be true. The other two prosecutors testified that there was no grant of immunity to Mr. Cosby and the lower court and the Superior Court both found that this was not true. All of what was alleged by Mr. Cosby's lawyers and the one prosecutor is beyond belief. No criminal prosecutor is going to immerse him or herself in a civil case that is going on at the same time. Moreover, for sake of argument, if the prosecutor actually did make a promise that Cosby could not be later prosecuted because of testimony he later gave in the civil case no prosecutor worth a grain of salt would have allowed for the case to proceed without putting the agreement to paper. If he did, he should be disbarred for his neglect to do something so basic. Somebody besides Mr. Cosby was a promised something out of the whole deal. As they say, follow the money.
