No, it is not.
You cannot insult a country's authority figures, or you undermine the legitimacy of the country's government.
It's the same "everywhere".

Of course, you can insult them in the privacy of your home, or when chatting with friends, but never to the face of those authority figures.... or you may faces charges.

I mouth off at police quite often... does that count? I only ever do it if they are hassling me for no good reason though, but because I walk a lot late at night they always stop me and try to search me. I never let them though.
