The UBS Banker Mule

If you didn't catch this
story in Portfolio Magazine, it's worth a read.  Here's a short extract:

Brad Birkenfeld, a Director for UBS Bank, "helped the very rich hide tens, if not hundreds, of millions of
dollars from U.S. tax authorities. He was willing to go the extra mile
for his clients, so he didn’t blink when one of them asked him to do
something that was blatantly illegal by any country’s standard: Buy
diamonds with secret Swiss funds and bring them into the U.S.
undeclared and undetected ... (so he) began jamming his clients’ loose diamonds into a
tube of toothpaste. Believing he had successfully masked the stones
from security screeners, he boarded his flight. He was wrong about the
disguise, though. Unlike cocaine, diamonds look exactly the same in an
X-ray as they do in plain sight, and toothpaste certainly doesn’t mask
that."
