How do these cases not result in mass prosecutions? It shouldn't be too hard to tie a few people to the abuse at these schools, then police say, "give us names and help us understand who was responsible at the top, or you're looking at many, many years in prison for child abuse and we'll just find someone else who'll talk" You know, the same way prosecutors go after mobsters and drug rings
In Luzerne County, PA, judges were paid off by local juvenile detention centers to sentence kids there. Over years, they sentenced many, many kids, in court, for absurdities (e.g., I think one kid was sentenced for throwing a sandwich at their teacher). Much of the court system and local legal community had to know; nobody put a stop to it. Judicial conduct boards and the PA Supreme Court were appealed to; they didn't act.
I forget how it finally came to light, but it got into the hands of federal rather than local state prosecutors. That's often how local corruption is stopped: the feds aren't tied to the local political system. The defendants, the Luzerne County judges, were clearly guilty of heinus crimes, ruining the lives of all these kids who spent high school in juvinile jail (imagine how your life would turn out). The federal prosecutors gave the defendants a sweetheart plea deal. Thankfully, the federal judge rejected the settlement and they were convicted and given long sentences.
(The Kids For Cash documentary tells the story.)
How does it not result in mass prosecutions? Look in the mirror. Me too. What corruption is going on in our communities? How about the IT community?
