I'm looking for what I think is a a short story, probably from the 70s or late 60s.
It's about a bank robbery where the lookout poses as a police officer. During the robbery, several people ask him (I think) for standard 70s-ish police help: a lost child asking for help finding their parent, a request to not give a parking ticket, that kind of thing. By the end of the story, he has a change of heart and turns himself - and his accomplices - in to the real police.
I believe it was written in American English, for initial publication in the US.
I'm fairly certain this was in print.
