You don't seem to understand how plea bargains work. Even I know what those are and how they work better than you. He admitted it, there was physical evidence. Here are the facts:
1. He gave a minor alcohol and drugs.
2. She said 'No' several times and even asked to be taken home.
3. He took advantage of her fears.
4. He raped her.
5. He admitted to it all.
I see what the problem is. You don't know the difference between a FACT and an ALLEGATION.
