The Guardian have an article by Jon Harvey, a Buckingham Town Councillor, giving 10 questions to ask PCCs. Apparently any worth their salt should be able to answer them.
Some are a little curious, others require some speculation. Question 9 would probably cause most a fair degree of puzzlement – (9. Is policing a complex business or a complicated one?) I’ve seen at least one definition of ‘complex’ that is ‘complicated’, which kind of finishes that one, unless your preferred reply begins “no, it’s really quite simple…”
More interestingly, what do you think of these questions, and do you have any better ones?

Sam – glad you liked the questions although you found some curious or speculative or both!
In my view there is a huge difference between the complex and the complicated: “The use of the term complex is often confused with the term complicated. In today’s systems, this is the difference between myriad connecting “stovepipes” and effective “integrated” solutions.[7] This means that complex is the opposite of independent, while complicated is the opposite of simple.” (http://en.wikipedia.org/wiki/Complexity)
So for me – policing is both complex and complicated – but different kinds of management and leadership are required to handle both aspects.
Hope that helps!
If you want to post answers to the questions on my blog – where a number already have (including two independent candidates) – please go to http://jonharveyassociates.blogspot.com/2012/02/ten-questions-for-potential-police-and.html
Many thanks for your interest.
