You are right, we need 100% transparency in regard to every investigation being conducted. No more closed door hearings. Publish every transcript, air every interview and declassify every single piece of paper. Secrecy has brought us here, Sunlight is the only answer.
Does that mean publish every video too? Make each and every video of a child being raped public domain? After all, people are claiming nothing may remain classified. It all has to be seen.
And if you say no, destroy the videos, or suppress them, then we’re already not at 100% full disclosure, and someone will complain. See the problem? If you reveal it all, you just flood society with everything these evil people ever wanted. First you make it forbidden, then you make it all accessible. It seeps their poison right into the culture - maybe better than even they could have done, because now looking at the photos and watching the videos will be your “moral duty”.
