About a century ago, I stumbled on a quotation from some Victorian geezer (which I didn't commit to memory, and I have several times since wished that I had).
His view - in a nutshell - was that Policing is a job that, to be done properly (let alone well) requires the very best kind of men, but somehow attracts quite another sort.
Posts from serving coppers like HTB, shine a light on how that works, it seems to me.
Basically throw out the statistics, don't be so keen to charge, don't look for kudos and if you can get to the heart of a really bad'un never get off his tail. A really bad one sent down is worth millions of tickets. 99% of the job is boredom and about 1% adrenalin. As for the rest a word in the shell like can save a lot of heartache. I took that to customs with me. I do hope I'm not talking out of turn as the cuzzie world was different.
