Afaik, Swedish police don't take bribes and generally don't commit criminal acts. At least not if compared with most other countries.

The main problem with Sweden is that the police is trusted to drink coffee instead of working. :-)

(That was a simplification, the Swedish police seems to mainly have organisational issues. The Finnish police is one of the most trusted societal functions there. I have never understood why a Swedish government won't head hunt top level Finnish police and fire the locals... Just the threat ought to be enough.)
