And as a private banker for UBS, Birkenfeld would help his clients invest, spend and move their money. One example he told us about involved withdrawing cash from a customer's account, buying some diamonds in Geneva and then smuggling them into the U.S. for the client inside a toothpaste tube. Birkenfeld claimed it was legal because the diamonds he said were worth less than $10,000 and didn't have to be declared at customs. "If it was legal why did you put them in a toothpaste tube? I'm having trouble with that," Kroft said. "Oh, it was just a way of carrying them so I wouldn't lose them. Where would you put two diamonds?" Birkenfeld replied. "I think I'd put them in a money belt or I think I'd put them in a case," Kroft said. "It was a one-time event. That's not my business. I just put them in a toothpaste tube," Birkenfeld replied. He told Kroft he wasn't trying to hide the diamonds from U.S. Customs. "Not at all," Birkenfeld said.
The interviewer started laughing when he said it was "just a way of carrying them". How can aperson lie so bad?
