OOoh an unpopular view
Yet one I happen to agree with.
Not for one moment suggesting anybody is 'above the law' or there aren't some clearly ridiculous decisions being made - but I would have thought most people signing up to the police are doing it to.. well... "try to make the world a better place" (only two (lovely) people I know who joined, did so for this very reason after finding their previous/better-paid jobs unfulfilling).
As with absolutely any profession, there are undoubtedly a decent selection of arseholes, but they do all seem to get tarred with the same brush way more than other professions.
Was brought home to me whilst chatting in the pub, when I was 'sssh-ed' for mentioning my friend's job out loud. They'd just told me in a somewhat shell-shocked tone what they'd been through that week, on my/our behalf, and whilst I wished to announce what they'd done to the world - they just wanted to keep their head down due to the abuse they'd get.
If I have a point, it would be that the entire "them and us" attitude is a problem and in all honesty, I think the fault lies with "us"
