I got stopped a few years ago in a Cavalier, just because i 'look' at the thick fuud the wrong way. i was then asked to show the 'kind officer' what was in my boot, i was then presented with his nose 3 mm away from mine and asked what the phuck my problem was?! Close enough for him to spit/slabber on my face while 'talking'. I seen that kind officer a few weeks later at the petrol station, out of uniform and on his own, he couldnt even look me in the eye. Amazing what a uniform will turn some idiots into.
On hind sight i should have gone straight to the police........ oh wait that was the police....
To be honest there are a few bad nasty apples out there but a few of my mates are coppers and the vast majority are completely spot on, unfortunately the few ruin it for the rest.
