What does PiS have to do with it?
What do you mean?
The question is why this wried act and why now.
Maybe it wasn't his first time, but this time someone took a photo and actually had the courage to report it to the police (he's PiS' prosecutor, after all):
This is what the witness at the shop said (who called the police):
"Chwyciłam za telefon, a wtedy sprzedawca powiedział, żebym nie robiła zdjęć, bo jest to znana osoba w Świdnicy. Nie obchodziło mnie to. Takie zachowania powinny być karane bez względu na to, kto kim jest."
"I took out the phone, but then the shop assistant told me not to take photos, because this person is famous in Świdnica. I didn't care about that. Such behaviour should be punished no matter who the person is."
