What's In The Unseen January 6th Footage?

Julie Kelly wrote a book on the January 6th 'Fedsurrection' and is ready for all 40k+ hours from the Capitol to be released. While the media continues to fear-monger the danger of 'selectively releasing footage', Kelly believes it will help give much needed answers to serious Jan. 6th questions. Is the DOJ worried about what the public might see that could exonerate rioters and incriminate the federal government?
