Suspects are rarely named in Germany. Privacy and all that.
Germany seems to balance personal rights and freedom of press differently, giving more weight to the former.
Coincidentally, the german Grundgesetz starts "Human dignity is inviolable", while the Bill of Rights starts "Congress shall make no law [...religion...] abridging the freedom of speech, or of the press".
Good solutions to any problem require consideration of interests, 'unlimited' does harm as well as good and such lack of balance is hard to deal with when you're on the receiving end of it (say as the victim of a false accusation or a crime that eventually leads to acquittal).
Also, those freedoms without limits were made long before the Internet and Google came along and those are game changers. Not to be able to adjust to changing times is a bad thing for any legal system.
It also differs a lot by police district, circumstances, and news outlet while the no-naming rule is held up relatively consistently.
Case in point: www.bz-berlin.de has an article about this case listing the full name of the suspect, the businesses in question and even a picture of one of them. For those who really need to know: She's Vietnamese.
Weird part being that her name is only mentioned because she supposedly gave an interview to the paper (while opening her door..), yet the only quote from her, in the whole article, is "I can't say anything, I don't know anything".
I know the US custom draws from the fear of secret courts, but I'm not in the least convinced it's worth the current price of defaming suspects.
Except when there is public interest, say politicians committing crimes, etc.
If there is a German native around that should lead us to the name in 10 minutes of phonebook/yelp digging that Marzahn street....
