For years, the LGT Bank in the tiny European principality of Liechtenstein, tucked between Austria and Switzerland, has been regarded as a safe haven for wealthy Americans trying to hide their money from the IRS. It helps that the reigning prince there, Hans-Adams II, and his family own the bank and strictly enforce the country's bank secrecy laws. "Liechtenstein is regarded as one of the most secretive places in the world," said John Christensen of the London-based Tax Justice Network. But all that changed when a disgruntled computer technician at LGT, Heinrich Kieber, downloaded all the names and secret accounts on to two CDs and turned them over to tax authorities in the US and Europe.
