Had a public defender been working his case, the lawyer would not have gotten the tapes from North Carolina because he or she could not have traveled there to litigate and appeal the ruling regarding the Fuhrman tapes. No amount of money can buy reasonable doubt. Bad evidence can only be found if the evidence is really bad. In this case, it was bad. No amount of money can change evidence, but money can find the mistakes if they occur.
Every story has two sides.
Each of us can tell a story that someone else who was present can describe in a different fashion. In science, we have no exclusionary rule. We look at all sorts of evidence, and yet, in science, we are often also wrong. Truth is a goal in a trial, but it is not the only goal. Even those who confess often do not tell the truth.
