I turned those off at the system level because the local authorities would abuse them to announce allegations of kidnapping, or license plate numbers of people who supposedly shot at cops and other such things that are not a threat to my life or safety (and thus not my business).

Apple, fortunately, in iOS 15 broke out the categories so you can turn off the "we want you to pay attention to this" crap from the police separately from the "here is critical information about something that might kill you".

Having them on the same category/priority before was massively irresponsible on the part of the police. I'm glad people with enough sense to understand alert fatigue eventually prevailed.
