I wouldn't. The worst the latter is likely to do is kill me. The former can do far worse if he feels like it.

Yeah, and go to prison for misconduct in public office. The UK isn't the US - there's no blue wall of silence, shameless police unions or anything of the sort. A policeman that breaks the law will be prosecuted - and regardless, the vast, vast majority of police-public interactions in the UK do not end in conflict.

Surveillance cameras on every street corner

Nothing wrong with those, and they're not illegal. Hardly the mark of a corrupt government...

the Snoopers Charter

You're citing a law. Literally a law. How is that even relevant to the conversation? Surveillance =/= corruption.

Brexit

Are you saying 51.9% of the country is corrupt? It was a referendum, you know. I'd go further and say Brexit is the prime example of the government not being corrupt - when the referendum didn't go their way, Cameron resigned and the cabinet was reshuffled, and the Tories, a party whose MPs were mostly against leaving the EU is dutifully following the will of their constituents.

You're being absolutely ridiculous. Corruption isn't "the government did things I don't like! waah!" Corruption is the abuse of public office for private benefit. You know, like not keeping your assets in a blind trust while you're POTUS, giving the highest cabinet positions to your biggest campaign donors, calling other world leaders to tell them to "hurry up" permits for your company's buildings... It goes on and on.
