Court considers validity of sex assault conviction of Bill Cosby

Pennsylvania’s highest court questioned whether Bill Cosby’s alleged history of intoxicating and sexually assaulting young women amounted to a signature crime pattern, given studies that show as many as half of all sexual assaults involve drugs or alcohol.

Cosby, 83, hopes to overturn his 2018 sex assault conviction because the judge let prosecutors call five other accusers who said Cosby treated them the same way he did his victim, Andrea Constand.
