Trainwreck director Judd Apatow is continuing his highly publicized criticism of Bill Cosby, who has been accused of sexual assault by numerous women.

The 47-year-old writer-director told PEOPLE Tuesday night that he felt there should be more outcry over the growing list of sexual assault claims against the comedian. Marty Singer, Cosby’s lawyer, denied the sexual assault allegations in November after multiple accusers spoke out, stating that the women were “coming out of nowhere.”

Apatow says he felt the public response was “too quiet,” and so he decided to voice his opinions.

“I thought, ‘Don’t we care about this?’ Eighty percent of women who have been raped don’t go to the police, so if you ignore all of these women, you’re sending a message to other women to not stand up for themselves, to not speak out,” Apatow says. “I wish everyone spoke out and I didn’t have to.”

He adds, “I think everyone knows that he did it now, because he admitted that he had seven prescriptions of quaaludes for the purpose of having sex with women.”

This comes after court documents from 2005, unsealed July 6, revealed the actor admitted to giving quaaludes to a young woman he had sex with.

Apatow has vocally condemned Cosby over the sexual assault claims on various media platforms. Most recently, Apatow sat down with Willie Geist, telling the Today anchor, “I think we have to stand up for the women and say, ‘We believe you.’ ”
