Billions (the tv show), of all places, made a somewhat similar argument in favor of post-hoc investigations, in the last episode.

Record and share everything immediately = no room for deals

Record nothing = too much room for corruption

So we land at... record everything + only review with just cause + strict whistleblower protections.

Which seems a nice splitting of the matter, but requires a strong, independent third party (e.g. judicial branch) to arbitrate access requests. With tremendous pressure and incentives to breach that limit.
