Even if they had reams of evidence showing Trump's guilt, it would never see the light of day. It would be devastating to the US to have that kind of scandal so there is plenty of incentive for even his haters to keep a lid on it. If it is true and it ever comes out, it will be well after his death and none of us will be alive to witness it.
I also think that there are so many wealthy people/politicians doing this stuff that there is a mutually assured destruction pact that keeps everyone silent. Who is going to risk opening those floodgates? They wouldn't dare to. We all know Creepy Uncle Joe has got some major skeletons in his closet, too. Think of Epstein's guest list: Dershowitz, Clinton, Woody Allen, Larry Summers, Bill Barr, Ken Starr, Kevin Spacey, Harvey Weinstein, etc. Hell, even Stephen Hawking wheeled his ass to pedo Island for some underage lap dances.
Plus, conspiracy theorists will have a field day if it looks like Pizzagate is a real thing. No way they are going to try to catch anyone important with this. They have to go after her to pretend they are still investigating, but no one important is going down for any of this. Unless they can somehow pin everything on Weinstein who is already in jail anyway.
