Because when you're research individuals you are crossing the line between 'just futzing around' and 'building up a file on a person without their consent'.
For instance, for NL:
https://www.justis.nl/producten/particuliere-beveiliging-en-...
The link you've given doesn't have any relevance to this, that's a page for registering a private security agency. I can assume you hallucinated the first answer and are now just linking random sources.
Reading comprehension not your strong suit?
Is there specific legal guidance about whether doing this in a training run is against the law? It seems like your link is for commercial / for-hire investigative work.
