Bill Cosby — Pennsylvania. Bill Cosby did not walk free because he wasn’t guilty of drugging and then sexually assaulting Andrea Constand in 2004 — or as he preferred to see it, of “dancing outside” of his marriage. De he escaped justice because a prosecutor’s office violated its previous agreement not to charge him. Go ahead and testify in a civil suit by Constand, they told him, because you’re not going to be charged. That deal was incredibly stupid, but it was also binding. Yet after Cosby waived his rights and implicated himself, a successor to the DA who’d made that agreement decided to charge him anyway. Which wasn’t either fair or constitutional.
