New York City's order for city employees to get vaccinated convinced a large fraction to do so.

However, some occupations have a substantial fraction of workers who have yielded to right-wng brainwashing; they would rather die than protect themselves and the public.

I regret that firefighters have fallen into this irrationality, because a right-wing fireman is probably a good fireman nonetheless. However, a right-wing cop is likely to be a racist thug, therefore a threat to public safety. It's good to get some of them off the force.
