I'm not sure what the word "residents" mean in this sentence.
The brutality of the ambush gave even the most hardened residents and detectives pause.
I assumed at first it means people who live nearby, but now I wonder if means doctors. The word is in parallel with "detectives", and the word "resident" has a meaning in the US of "a doctor who is training in a hospital".
What does the word "residents" in this sentence refer to exactly?
