Besides Switzerland, attention should also be on small principalities and city-states that don't necessarily have the same laws as 'normal' countries. Think Andorra, Lichtenstein, Gibraltar, some of the little islands like Nauru & Kitts, City of London, Vatican City… and even off-planet colonies on the Moon/Mars that might have been established without public notice.
Why did Obama sign a law late in his second term protecting companies from prosecution if they do something in outer space that would normally be a crime within the territory of the USA? Think, Anons!
