Indeed, this information can transpire in court, but it shouldn't be the People's only avenue to RECEIVE such intel. If this were to be the case, the courts would have leverage to transparency, whereas the People should have both.
You shouldn't NEED the court to start your search on proving damage from the State. You don't NEED to wait for a courthouse summons to know your rights were violated. If your prerequisites to be upset are explicitly the actions and behaviors that occur in judicial proceedings, then this country is far gone. If that's the one area you want to protect to the largest extent, then bad actors will use every other step before that one (including arrest) against you - and that's where radio comms come in.

Not sure where you're getting that from. As I stated before, in person recording should have more and better information. This does not require a court.
The people most likely to benefit from the recordings are the ones in contact. The recordings are a terrible small piece of information and are generally self-censored. Better of recording everything in person.
