Just off the top of my head:
The guy who owns Comet Pizza, Alefantis, was listed as one of the most influential people in DC, where there are plenty of influential people. He's associated with John Podesta and Podesta's brother Tony, pointmen of the Hildog Clinton campaign, an offshoot of the presidency of the guy who made something like 26 trips to a disgraced island, and both brothers collect artwork of raped children. Dennis Hastert, longest serving Republican Speaker of the House and long time associate of the Podestas, was convicted of kid fiddling.
To say nothing of the legion of Epstein associates. Epstein was hired to teach at the uber-expensive Dalton School, which could have had its pick of very qualified applicants, despite not even having a college degree. He was hired all the way back in the 70s by Donald Barr, father of Bill Barr the AG who described Epstein's death as a perfect storm of screw ups.
None of this means kids are held prisoner under a DC pizza parlor. But it's not like there's nothing there either. You don't have to play 7 degrees of Kevin Bacon to construct a conspiracy theory. There are repeated perfect storms of coincidence involving DC and world elites and young people.
Imo there's a whole lot of blackmail going on and has been for a long time.
