Context is everything.
In an unusual or highly charged situation, one must choose a course of action carefully and lay the ego aside. Not always easy.
This is why it is a good idea to occasionally watch cop and emergency shows, to provide examples and to think about what to do. Then one has formulated at least some general rules.
Medics and firefighters -- I will follow their instructions. They are in the thick of it, and they are highly trained. Their focus is frequently on individuals.
I keep away from police officers if at all possible. They must deal with perps, and I am not going to get in their way. We are not talking about traffic jams here.
I will take my own counsel when bureaucrats try to manage a disaster situation. I learned this first hand when I was stranded in very heavy ashfall from Mt St Helens in 1980.
To repeat -- Context is everything. When your life is on the line there is no place for ego posturing, like the guy with the cervical injury. If you have insufficient information or skills, admit it, get over it, and get help. If a bureaucrat tells you you must have an emergency vaccination, have your decision already made.
