I'd forgotten that Federal law's 1 party consent is as extensive as it is, & hadn't included that above. That is an important consideration.
To be honest, I'm not sure how I feel about states creating their own privacy laws. Part of me agrees, that 1 party consent is probably all that's required, and to do more creates a danger that criminal activity can use the law to protect itself.
Oregon did exempt two specific classes of speech: any speech talking about a felony that endangers human life, and any speech by police officers. This gives the public some right to 1 party record really bad things.
What's so weird here is that the court used those exemptions to strike down the entire law. They said that since the law discriminates, since these people aren't protected, it jeopardizes their right to speech. And they used that to invalidate all of the state's attempt to create additional privacy for citizens. I'm not sure how I feel on 2 party consent entirely, but this seemed like an attempt to create a somewhat balanced, privacy-sensitive approach, and seeing it taken down like this makes me feel embarrassed for the courts, that the federal courts would so brazenly & broadly undo the state legislature. I'm undecided about 2 part consent, but this feels like a vicious stroke by the courts.
