Janice Dickinson -- Bill Cosby Needs to Confess One More Thing (VIDEO)

Janice Dickinson isn't satisfied with Bill Cosby's admission he used drugs to sedate at least one woman -- she says he STILL owes her, and all his fans, much more.

Janice told us Cosby's deposition confession is just the start, and believes he should admit being a "mass rapist." She also singles out some other celebs he needs to pay back ... big time.

Similarly, model Beverly Johnson, told 'Today' she doesn't feel "vindicated," but hopes the dozens of other women who've come forward take some solace in the truth coming to light.

Interestingly ... a bust of Cosby was still standing at the Walt Disney World Resort in Orlando ... until Wednesday morning, when Disney responded to a petition to remove it.
