In fact there is currently a fairly noteworthy case ongoing in Germany about a Gina-Lisa Lohfink. She's currently trying to repeal a court decision forcing her to pay money to her rapist. The rapist was considered innocent despite clear video evidence because she didn't use force to defend herself and there was no evidence of her being drugged (although the video clearly shows her being totally out of it).
If you're a victim of rape in Germany, you really don't want to go to the police unless you're absolutely sure you fit all the boxes and you definitely don't want to call out a rapist under your real name.
