Why are people so down on the police?

Opinionated generalisations are the trademark of someone who doesn't have the intelligence or knowledge to construct a convincing argument that will stand up to cross examination. You are now typecasting yourself into the role of 'provocateur' in order to avoid the fact that the few examples you gave really didn't amount to much, and that your 'argument' as a whole amounts to nothing more than sermonising.

You really shouldn't allow yourself to be so sanctimonious.

Not at all, the examples I gave all demonstrate my point and there are plenty of others on the forum should you care to look for them. And I'm not the only person on this thread who believes this to be the case. Of course there was an element of provocation to my opening post but that's plain to see. As for being sanctimonious - so what? You're behaving no differently. Besides, you've got 'troll' written all over you, have only just gotten over your fit of potty-mouth, and haven't added anything of real relevance to the subject.
