This is what so many people miss.

Any time you have power over the public (e.g., a cop), or present yourself as an expert in a way the affects the public (e.g., a medical doctor, civil engineer, politician) then by default you should be held to a much higher standard than the general public. There should be very little room for error or mistake and all errors/mistakes should be scrutinized for malpractice. The burden should be on the expert to prove they are qualified and should be allowed ("licensed") to hold the position.

If you can't handle that then find another profession.
