I am happy with their lack of expertise and hope it stays that way, because I cannot remember a single case where redactions put the citizenry at a better place for it.

Of course if it's in the middle of an investigation it can spoil the investigation, allow criminals to cover their tracks, allow escape.

In such case the document should be vetted by competent and honest officials to judge whether it is timely to release it, or whether suppressing it just ensures that investigation is never concluded, extending a forever renewed cover to the criminals.
