Important detail that is missing in the article and that some are getting wrong in the comments: This is not about forcing messengers to add backdoors for mass surveillance or weakening the messenger/its encryption in general (although that indeed is the wet dream of some governments/agencies). It’s about infecting the phone/device of a suspect with spyware (either by hacking remotely or with physical access, although in secret of course) and sniffing their communication before it’s encrypted/leaves the devices (or after decryption for incoming messages). Every case must be individually approved by several judges so cops can’t just use this willy-nilly, the crime they’re investigating must be quite serious (punishable by at least 10 years in prison) and it’s limited to 30 cases per year.
I think it was hard because we had to learn all that abstract advanced stuff (Plusquamperfekt Futur II Temporaladverbial Reflexivpronomen, all that shit) that you’ll probably not learn in a language course for non-native speakers and that you don’t need to know to speak the language in normal life.
