Sure, eventually, after decades went by and a cut and dry criminal case got dismissed because he was an alleged intelligence asset. But because of public scrutiny, largely because a dissident president named Donald Trump talked about the Epstein island issues on live television in a bid to damage his political opponents, he did eventually go to prison.
If it hadn't been politically expedient for a billionaire to attack him for political points, it never would have been an issue of public concern, and Epstein would still be trafficking children for sexual abuse. Everyone knew about Epstein for years and he was personally exempted from the consequences of his actions. While Epstein is now gone, there are going to be dozens of other well connected child sex traffickers similarly generating blackmail on politicians just like Epstein and Maxwell did, and they will continue to evade the criminal justice system.
Most importantly, the feds seized all of Epstein's files and CDs and that was the last thing we heard of any of it. Zero people have been punished for raping children. The only person to get materially punished for it is Richard Stallman, who only spoke in defense of one of the alleged rapists who visited the island. Nobody else has seen an ounce of heat. No lost jobs. No criminal charges.
