So the smiley I'd need for my big grin right now, I don't have in my repertoire: The Munich law firm Gravenreuth & Syndikus, which in the past drew attention primarily through cease-and-desist letters, was also searched. One of the lawyers, Bernhard Syndikus, was taken into custody due to suspicion of obstruction of justice and flight risk.
Update: the Tagesspiegel has more information.
I found the original article at Die wunderbare Welt von Isotopp.
