The Police have good and bad, like any organisation.
However, I don't think all these reality police car chase programmes help, as invariable the police individuals come across as arrogant tosspots, playing to the camera, and the voiceover narration adds to this.
I've been pulled far more times than I care to remember, some deserved, some not, but apart from the odd sarcastic attempt at humour, which often backfired (esp if it was an undeserved tug), I have mostly been treated with dignity and respect, and generally have no issues whatsoever with frontline officers... ...quite the opposite, I wouldn't fancy their job.
But during the last armed robbery at bro's shop, a little old lady, the wrong side of 60, had to stand up to armed robbers, because the police refused to attend until the danger had passed - literally "call back when they have left". And my mum's last burglary, caught on CCTV, the police admitted they knew who it was, but not further investigation. Then the fact that the (seemingly) entire Towcester police station use liveried company cars to drive 4 miles down to the Super Sausage on a Friday morning really doesn't help with public perception - nobody begrudges then a break, but to do some so publically, and misusing company property that we all pay for, doesn't help with images. I've even seen them use B&Ts to get there.
