CA make exceptions for most violent crimes (including kidnapping) and extortion and blackmail. Also, any statement in a public area or outdoors is generally admissible (it becomes the burden of the counterparty to show that an expectation of privacy would arise). And importantly, these exceptions are only required in two-party-consent jurisdictions, of which there are only about a dozen. The remaining states are one-party consent. Most of Europe is one-party consent.
