What are you talking about? The most common form of evidence introduced in every trial is first hand testimony. And a lot of women are willing to offer first hand testimony that Cosby raped them. Granted, a jury could claim they were not persuaded, but that testimony was certainly evidence. And when there are dozens of witnesses offering testimony to a consistently common pattern of behavior, it becomes pretty powerful evidence.
“The most common form of evidence introduced in every trial is first hand testimony.”
Accusations made to the media aren’t testimony.
