Some of the more interesting cases of fraud have to do with people who take on a new identity and promote themselves as self-proclaimed charity money raisers. They convince their followers to contribute money to good causes. But they then pocket the entire amount. This tactic is both fraud and embezzlement.
I've heard of some people, who have fraudulently gotten a doctor's credentials or credentials for other professions, and actually practiced for several years until they were caught.
You see fraud from the highest levels of society down to fraud between a husband and wife. It seems like some of the smartest and cleverest people get into the fraud game!
