Why are people so down on the police?

In my opinion people should stop complaining about the police.

Why? If they do a shit job why should we keep quiet about it?

I don't think they always do the right thing, but can we expect perfection from everybody?

Perfection? Of course not. But high standars? Certainly. And a lack of perfection can be made up by a willingness to accept fault, learn from mistakes and not fall into repeat failings - something the police (based on anecdotal evidence) seem unwilling or very slow to do.

I see many other professionals who do a crap job and never get bitched about and I can't claim to have never been negligent in my own work.

Firstly, I think you'll find that whenever public service is involved doing a crap job will result in bitching. Secondly, a crap job by the police, much more so than most other jobs, undermines the basis upon which are civil liberties and freedoms are upheld. You may be crap at your job (whatever it is you do) but I really doubt that it affects me either directly or indirectly. A crap job by the police, whose duty is to uphold and protect our civil rights, affects me indirectly and possibly directly.

Maybe we should do "job swap" and see how easy it is to do
Or maybe we should do an international police exchange and have police from russia for a week, maybe that would open some eyes.

The fact that other countries have a shittier police force than us is not an excuse for poor performance of our own police force. Especially not given the amount of public funding that goes to the police and that we live in a country that claims to be ahead of many others in terms of democracy and protection of the rights and freedoms of its people.

Also, this is a poor, poor argument by the way. There will always be someone or some place worse off than you - does that mean you should not complain? Think about that next time you have a shit and run out of toilet paper. You would probably not like someone to tell you to stop complaining and that you should try living in a country where they don't even have toilets let alone TP and see how you like that.
