This is more than just a wild stab, this is the real deal. Federal criminal indictments have an astonishingly high conviction rate in this country, like over 80 93 percent. Because so much more is required of federal prosecutors. You can't just convince a federal judge that there is probable cause, like in state court. You have to win over a federal grand jury to get the indictment. Especially with corruption, conspiracy, racketeering, wire fraud-type cases, a federal prosecutor is not going to move forward on something this high profile without airtight evidence and testimony. There's probably reams and gigabytes of rock solid financial records and emails, I bet. The fact the Swiss are swiftly assisting with arrests and extradition seals it, for me.
There's also no parole in federal prison. And there are sentence enhancements to the moon for these kinds of white-collar crimes under federal sentencing guidelin
