It is a good read and in my opinion solidly argued.
They cannot really make a case for the body cam footage not being used as evidence when the court watched it, commented on its content, and relied on it during a hearing, and it was additionally cited 6 times as evidence in the brief presented.
I think this is the strongest argument why the footage should be made public again.
The "privacy of minors" concern is idiotic, since their faces are consistently blurred in footage or the relevant portions cut out as a remedy.
