Several years ago, my wife and I invested in a project called "Sanctuary Belize" and, like many of the investors, we were incredibly excited about the prospect of retiring in paradise. After a time, things just weren't adding up. The company supposedly put controls in place to reverse course, but we exited the project. As it turned out, those controls either were not put in place or failed. The U.S. Federal Trade Commission last week announced that it had shut the thing down, and highlighted it as one of the largest scams in its history.
