Watching a rerun of Quincy (my pastime often in the afternoon, so to speak, especially when I’m under the weather, as now) and the following exchange took place. (Quincy is talking to a cop about an incident of death by hazing, which appears to have been accidental).
“Well, aren’t you going to charge them with anything?”
“Quincy, what am I supposed to charge them with?”
“Ask a Philadelphia lawyer! I don’t know.”
The series is set in LA and Philadelphia has nothing at all to do with the story so the question arises, is this a proverbial expression in the US?
