"This Regulation does not apply to the processing of personal data:

* "by a natural person in the course of a purely personal or household activity;
* "by competent authorities for the purposes of the prevention, investigation, detection or prosecution of criminal offences or the execution of criminal penalties, including the safeguarding against and the prevention of threats to public security."
I thought the GDPR sign at the butcher shop was a joke?
What if this person had a hobby of simply collecting and cataloging information bout people they come in contact with?
Then they are a data controller.
"A data controller is the individual or the legal person who controls and is responsible for the keeping and use of personal information on computer or in structured manual files.
(...)
In essence, you are a data controller if you can answer YES to the following question: Do you keep or process any information about living people?"

Hopefully this'll go to court and set a precedent that more in line with the spirit of the gdpr.
Of the western world we have the US, UK, and Canada that employ common law where precedent really matters.
In most of the EU the system of civil law is used, where the judiciary is expected to be much more literal and to not perform much interpretation or reference to previous interpretations.
It's still secondary to the statute and not 100% binding, but nevertheless it is a real part of the system.
Also, both the US and Canada have a civil law jurisdiction: Louisiana and Quebec, respectively.
Both do make some use of common law as well, but private law (governing relations between non-state parties) is even now predominantly civil law in both places.
If the original actors in this case were non-state parties, I expect that civil law would be applicable to a hypothetical Quebec version of this dispute. In Louisiana, same thing if the relevant law was at the state level rather than federal. (In Quebec, even federal laws are interpreted using civil law principles when covering private law topics.)
