Same with medical professionals. Medical errors kills over 250k people each year in the US. It generally isn't criminal if they make a judgement that results in someone's death. There's been a number of serial killers in medicine because we give medical professionals the benefit of the doubt due to the nature of the profession.
My point is that these professions aren't your average jobs. It's normal for doctors and police to deal with life and death, and to make decisions that could set off a sequence of events that quickly results in death. So either we have to say that nobody deserves to make these decisions, or we have to hold them to realistic standards.
