At no point did I indicate I don't value blue collar workers such as plumbers or construction workers, quite the opposite. At most I said the police were low paid blue collar workers - and in general I do believe most blue collar workers are underpaid. For what it's worth, I do also value our police forces, even with their flaws. But a blue collar profession has a different set of knowledge handling than a white collar one - it's not that one is better or worse, but they are intrinsically different ways of knowing.

You're correct and my comment is US centric. What I find interesting is that some US cities have seemingly moved farther from a more educated police force, removing requirements around having college degrees and reducing trainings.
