Cop Swap.
The title rhymes so it's catchy.
Each episode involves a precinct of cops from other areas in the world being swapped with US police precincts. You could have a precinct of Dutch cops move to the US for a month and replace a precinct of US cops who'd move to Denmark for a month.
Imagine the Danish cops arriving at Oak Park the worst neighbor in Chicago where over 4,000 shootings happened last year. Imagine the US cops trying to catch bicycle riders in Denmark.
But it could be anywhere in the US, like rural Appalachia or where a bunch of Amish live.
Lot's of "lost in translation" stuff. Lot's of dealing with new and unexpected situations.
It would be restricted to Europe we could swap Japanese cops with US cops for example.
