Wait until you see who's in charge of deciding who to prosecute! My first experience with German police was reporting a crime and then then discussing if they should arrest me for being involved with the crime, since I was there at the police station and therefore easier to arrest than the actual perpetrators.
In the UK, when I reported a crime, I had to pull out the book and read the verse what constitutes an assault for Police to record it, because they didn't know. That said, 3 weeks later case was closed because they couldn't find the perpetrator. That is despite me giving them video evidence and address of that person. Looks like our taxes are well spent.
