The old joke goes that a lost motorist stops in Carmarthen and asks a shopkeeper for directions to Carlisle with the pithy response, “Well I wouldn’t start from here”.
This is often how the debate on the fact that there are 43 separate police forces in England and Wales starts: if we were to draw the map anew, we wouldn’t start from here.
This begs the question: if you are to merge forces, where are the obvious places to start?
