I sometimes wonder if US prosecution of these "crimes" is more about attempting to drain the defendant of money through legal fees rather than trying to get any sort of conviction.
The way the US legal system works, a conviction is frequently only possible if a rich defendant is first drained of money.
This has nothing to do with innocence or guilt.
It is also a show of force intended to deter others from trying .
Its like the drug war- after the US went after Escobar and Noriega nothing changed. Someone will always step in to fill the void.
