As John Dean said to Richard Nixon 'What an enthralling prospect'.
Swiss bankers and politicians are the soulless moneymen of death and destruction in our World. They need to answer, because they are bad, bad people. Historical friends and supporters of: various royals, Oil Sheiks, Vatican embezzlers, Hitler, Stalin, Medellin drug merchants, Marcos, Khadaffi, Mugabe, Saddam, Castro, and unknown numbers of world and American political, diplomatic and economic behemoths banking their freelance and unsavory resources. Since Vince Foster traveled to Zurich on several one day trips, I'll bet the Clintons have an account with one of those fine banking institutions. Were his African trips and Chinese liasons about kickbacks? That wouldn't be like him.
It'll never happen though. Politicians aren't going to rip open THAT hornet's nest. For the same general reason that the town brothel was never raided - the mayor, police chief and judge were regular customers.
