I'm not comparing it to E2EE. I'm stating there is personal information in the messages. The subject doesn't have a choice to how that information is transmitted or protected. There should be a duty for the government to protect that person's info if they have the power to force the person to disclose it.

Most recording are not by default public record either. Oftentimes it needs to be censored before being released to protect sensitive information, like subject addresses, license numbers, etc.
