Photos of an illegality – can I be photographed?

Dear community, if I were not so angry about it, it would probably go smoothly as a “witness to the weekend”… I live in a side street (Tempo 30), where a school is currently being built extensively; many traffic signs and massive barriers. To get there through and again to the road, I drove along such a barrier about 30 meters on the pavement – on which nobody was – of the highest pace. At the end of this “side street of an I answered him: “Excuse me!” and his comment on it was: “Nothing with excuse! This will have consequences for you, you will still be very, very surprised” (!). – During this harsh dialogue he always had his cell phone in his hand, and took numerous photos of me and my scooter. – My Fr. “Objective” is of course right; the passage on this road was not allowed. Should I actually receive a warning fee for this reason, I will pay it. – What really concerns me, however, is how to react to such a “bagatelle” with such an “aggression” at all (“Nix with excuse! This will have consequences for you, you will still be very, very surprised” (!). – A “John Wayne” of an 80 meter long side, side road… – d he certainly took numerous photos of me, my scooter, and the license plate with his cell phone (because clearly recognizable). – Personally, I believe that something like this is simply going too far! – Please: Your opinion.
