Sorry if this is a touchy subject, but under what evidence was bill cosby convicted? And how are most sexual assault cases determined as even with dna evidence, many suspects would just claim it was consensual? I hope to god this doesn't get obliterated because people think I'm asking for tips on how to get away with rape like that other famous topic. I just read the cosby articles and realized he got convicted from a rape he did in 2004. I'm assuming there would be no evidence from then?! How was he able to get convicted then?
