This is patently unconstitutional and unlikely to stand, but de Blasio’s omission is noteworthy. As he has assiduously courted support from Muslim advocates and Islamic groups, it is unlikely that the existence of mosques in New York just slipped his mind. He threatens those whom he knows are susceptible to threats, and not those among whom are some people who are not only his allies but who are unlikely to submit to either the coronavirus prohibitions or his threats.

“De Blasio: Synagogues That Defy COVID-19 Restrictions Will Close Permanently If Necessary,” by Hana Levi Julian, Jewish Press, March 28, 2020 (thanks to the Geller Report):

“A small number religious communities, specific churches, specific synagogues are unfortunately not paying attention to this guidance even though it’s so widespread. So I want to say to all those who are preparing for the potential of religious services this weekend, if you go to your synagogue, if you go to your church, and attempt to hold services after having been told so often not to, our enforcement agents will have no choice but to shut down those services.

“I don’t say that with any joy. It’s the last thing I would like to do, because I understand how important people’s faiths are to them, and we need our faith in this time of crisis. But we do not need gatherings that will endanger people.”

“Everyone has been instructed that if they see worship services going on, they will go to the officials of that congregation and inform them that they need to stop the services and disperse.

“If that does not happen, they will take additional action up to the point of fines and potentially closing the building permanently. Again, that will begin this weekend….
