Personally, I suspect that the general public in the UK where I live have a skewed perception of what professionals do in many walks of life due to the mainstream media TV shows, dramas, soap operas, and movies. This leads people to believe that doctors, nurses, and police officers all do things that they don't really do.
On TV shows we see teams of people working in depth on a case using vast amounts of resources and technology and dedicated detectives going the extra mile to devote the entire meaning of their life to uncovering the truth behind an incident. Obviously the reality often is way more tragic, pathetic, sad, and inconclusive, plus errors or failings are common
