The layout of the Capito building including sections that can be considered a security threat if made public.You don't expect anything new from over 40,000 hours of video Nancy Pelosi did not allow to be released to the public? Yeah, we've seen maybe a couple of dozen hours, what possibly could be in those 40,000 hours Nancy wanted to be hidden?
I will tell you what will likely happen. Carlson will highlight some footage that show maybe some friendly interactions between cops and people inside the Capitol. Maybe some people doing some benign things, and then use that footage to further the narrative that Jan 6th was no big deal.
He will not show the actual footage that shows people attacking cops, destroying windows to get in, or any unruly or violent behavior.
In the end it will not change that 140 police officers got injured and several people died. Nor will those facts convince you that Jan 6th was bad.
See, unless I'm very much mistaking you are one of the people who still believe Tucker Carlson is acting in good faith despite emails coming out him flat out admitting to lying for ratings.
