What do you mean by "hiding the truth"? If I think Facebook stock is going to go to shit, should I tell you that before I sell you my shares? If I'm the CEO of Apple or Wal-Mart or Amazon, should I be held criminally liable for contracting to aggressively shift risk from myself to suppliers?
The line between aggressive business decisions and criminal ones can be a thin one. Financial crimes are in fact a relatively new invention. Did you know that at common law, embezzlement wasn't a crime? It took a long time for the law to come to terms with the idea that there should be anything illegal about doing something with money someone voluntarily gave to you.
