I've never felt uneasy around British police officers. The Metropolitan Police were particularly helpful to me on two occasions. I'm just a somewhat frequent visitor, though. However, the British police have a rather good reputation they mostly live up to in my opinion.

Police in Germany are good as well in that respect. Mostly polite and to the point. Never needlessly aggressive.

I do feel uneasy about the police as a system though and what it's about to become. Home security (or whatever euphemistic term that's called nowadays), politicians and police representatives arguing for ever more surveillance and authoritarian measures. That's what's undermining police work in almost every Western country no matter how good and trustworthy the police in those countries actually might be.
