Who was killed for not following the rules? If you’re referring to Mahsa Amini, surveillance footage shows she collapsed mid-conversation which is a far cry from the “beaten to death for not wearing her hijab” story that was repeated as nauseam.

Certainly in many countries violation of legal due process occurs, but Iranians aren’t keen on burning the country to the ground for matters of hijab or enforcement mishandling. The pro-government demonstrations in Iran have been magnitudes larger than the riots, though you wouldn’t know that if you’re only tuned in to western sources.
