German police start measuring distances between people with folding rulers

It would be dangerous to point one of those at someone's nose, a wrong movement or an accidental push and an eye could be seriously harmed.
It does bother me when the police is enforcing one thing ( the distance ) because they want to break another thing ( the protest ).
This is not clear from the footage.
That would be the law in question.
Unfortunately this creates a sort of self-fulfilling prophecy because these folks view themselves as persecuted victims in some sort of covert world war. (Last year, a woman from Kassel even compared herself to resistance fighter Sophie Scholl who was executed by the Nazis [0][1])
The whole contrarian scene here is somewhere between crazy and ruthless by now. Earlier in the pandemic there were parents who took their children to protests to make the police refrain from using water cannons on them [2]. Recently a man from that scene killed his wife and their three daughters because they were caught buying a faked vaccination passport for his wife and were afraid what might happen to them [3]. In another incident, a man shot a student gas station employee after the worker asked him to wear a mask [4]. They're completely out of their minds by now.

This was speculated about ( fear mongered if you will ) in the beginning.
AFAIK, it never happened.
