- If the state can impose these kinds of regulations, presumably a wholesale ban wouldn’t have been entirely impossible, so why did the city keep saying that it was?I think the answer is pretty simple: They actually could have, but for political reasons did not want to admit it. This is very troubling, as it makes for an interesting discussion as to how much the government should be allowed to insert itself into religious rituals - and what, in the future, the government may decide to impose control over.
What's sad is that in this case, some Jews essentially forced this upon themselves. The precautions listed are normal, common sense practices which should have been followed in the first place - but because people did not follow them and there were problems, the government felt it had to mandate the procedure. It's very difficult to fight the government on this, as their requirements are completely normal and fair, but this now allows for future instances where the government can impose control over religious ceremonies.
This case also has interesting parallels with other issues, such as how involved the government should be in other situations versus this one, from national security to homosexuality. Certainly, though, one who agrees that the government should be involved in this case, where very few are affected, would want the same involvement in matters of national security when many more are affected. It will be interesting to see what side people come down on in this case.
