You're saying this like the laws aren't different in other countries without these issues arising. It's reasonable to argue that a police officer on duty is exempt from the expectation of privacy and indeed many such countries have exemptions for police officers on duty. It's also reasonable to have different expectations of privacy for people "of public interest" (i.e. celebrities, politicians and extremely wealthy business moguls) and indeed many such countries do distinguish between what privacy you can expect as an ordinary individual or someone whose job literally involves having their face frequently appear in public media. Your response is very American too, by the way: while you are concerned about state oppression (or rather: the ability to record state oppression) I'm concerned about the oppression by both businesses and the state that a complete absence of an expectation of privacy outside well-defined private spaces enables. Specifically it trivial to justify mass surveillance and various forms of harassment.
