Jaap-Henk Hoepman in his article Good riddance to lawful hacking explains that there is no need for law enforcement to get access to private communications:

The amount of data available to law enforcement is staggering. Even if they can no longer listen in to our communications or read our messages, the metadata (who we are talking to, when, how often, and how much) is still available to them. Law enforcement can track our locations, either through data brokers that in turn get their data form the location based services we use on our phones, or by asking the mobile network operators for the current location of our phones. Camera surveillance is increasing, especially as more and more people attach video doorbells like Amazon’s Ring next to their front door, or by people wearing Meta’s AI glasses. Perhaps the only caveat is this: metadata is mostly circumstantial evidence, that does not necessarily prove without any doubt that someone was indeed involved in perpetrating a crime. Access to data (e.g. pictures or video footage) or messages may be needed to seal a case.

Hopefully, the European legislator will realise that encryption and other protective measures are essential for citizens to protect themselves against criminals and other unsavoury characters.
