I guess, what can we as ordinary citizens do about the world’s most powerful people, Presidents, princes, CEOs, billionaires, in a giant child rape ring going unpunished? Just shake our fists at the sky? What can we do?
Present evidence in a court of law. I'm sure there are enough detectives, prosecutors and FBI agents eager to make a career out of bringing a case if there's solid evidence.
Yes, that evidence conveniently “suicided”...
With a crime as widespread as you suggest there will likely be other witnesses like the woman currently accusing Prince Andrew.
That woman is very brave, but the threat of death will make many witnesses think twice about coming forward.
