I live across the river from Mainz, so I can make a couple of comments on this.
First, any idiot who puts on a jacket or vest that says “Police” in any fashion and isn’t a cop....violates the law and gets dragged into court. If you use the word “security”...that’s ok. I imagine these guys will get smart after a couple of meetings with the cops.
Second, their methods might work on 13 and 14-year old Muslims in the area. But these seventeen year old teens....won’t take these guys serious.
Third, In the urban area of Mainz (center point of the city)....I’d say the density is around ten percent of the population. But the area is surrounded by pubs and beer gardens, where you will see various Muslim guys after work. They’ve worked through a hard physical day, and don’t usually tend to take this ethical police guys too serious.
Finally, somewhere in the midst of this....the German cops have to be asking...who arrived in the last year and started this line of religious indoctrination. It’s not a local guy or a new resident from Turkey....it’s someone who likely arrived in from Saudi Arabia. They will eyeball this whole line of change and how it started, and identify the source.
I used to go to Mainz quite often when I worked for IBM. Great city and especially nice to be there during Christmas time.
Mainz is just the byline. This happened (per the article) in Wuppertal which is thick with these kind of filth. Don’t think they’d try it in, say, Leipzig. Also, their vests actually said “Police” in English, not “Polizei” so I doubt it’s even illegal.
