Never was a fan of Cosby, but this reeks of opportunism.
I mean, it's all set up for profit, just look:
1. These girls were under the influence of something during sex.
2. Cosby is rich.
3. All of these events happened a long time ago.
4. The current cultural climate is extremely sympathetic to rape victims.
Literally all these women have to do is claim that they didn't consent to the drug taking, and Cosby becomes a serial rapist, and they all profit. There is essentially no risk for these women to make these claims, because they can't be proven wrong. On the other hand, Cosby is already ruined in both life and legacy.
