>> Bill Cosby back in court Wednesday after a day of heated exchanges between the defense and prosecution. A Pennsylvania judge will decide if up to 13 accusers can take the stand at Cosby's criminal sexual trial next year. The disgraced comedian faces sexual assault allegations from dozens of women.
Former Temple University basketball coach Andrea Constand's case is the only one resulting in criminal prosecution. Testimony from the additional witnesses will help the prosecution present a portrait of Cosby as a serial sexual predator. Reuters' Joseph Axe is at the courthouse.>> Prosecutors are typically barred from introducing what's known as prior bad acts as evidence against a criminal defendant.
The idea being that you don't wanna prejudice jurors against the defendant for crimes or behavior in the past that have nothing to do with the instant case. However, under Pennsylvania state law there is an exception. If prosecutors can demonstrate that the crime in question was part of a longstanding pattern of behavior, judges will sometimes allow them to introduce evidence of that pattern, that is prior bad acts, in those cases.
>> The defense is expected to question the reliability of the accusers. Cosby continues to maintain his innocence.
