privacy for the accused who are considered innocent until the verdict is read is one reason.

I really doubt that's why. Court proceedings are a matter of public record. You can just buy magazines full of names and mugshots of people who gave been arrested. I want recordings to keep power hungry judges in check.

It is two completely different things to release the records while the trial is going on and release the records once the trial is decided. The latter is completely OK and wanted, the former is undesirable.
