Testimonies aint shit tho. I seen a lot of case where there was zero evidence and the accused was found guilty, and the exact opposite when there was substantial evidence. I know someone who personally got raped, and the rapist got off. Rape cases are very wishy washy that way, depends on the people behind it.
There was evidence against MJ, albeit not concrete, but the testifiers lied, both times. There was no real evidence on Pac, but the accuser was believeable enough to where they found him guilty. Remember the Duke scandal? It seemed believable, but the accuser admitted to lying. If you can make the person look bad enough and hold your story together, you can accuse anyone of rape.
