Because it isnt a list of sex offenders. Its a list of contacts, clients, whatever. Just having a name on a list from Epstein doesn't mean anything beyond being suspicious. It doesn't prove anything by itself. But the public doesn't care about that. So the people on that list need to be protected, they are innocent until proven guilty. You can't and shouldn't want to make it public.
There is no deep conspiracy necessary. Although powerful people are implicated due to being on the list, or actually did things that are fucked up. The fact none of it got public isnt proof of conspiracy, rather of a functioning legal system. And it wouldnt surprise me if these papers simply never got handed over to any politician, despite their claims.
And them asking stupid questions like 'hand me over the list of child molesters that epstein made'...which doesn't exist. Lets not forget that most of these Trumpets are exceedingly dumb.
