The result of the swiss banks of Zurich: they believe they are
answerable to no laws save their own.
In the aftermath of WWII, tons of priceless art, antiquities and
precious items were looted from the conquered lands of the third
reich and hoarded in such 'secretive banks'. Upon demand, the swiss
banks refused to surrender the contraband even under pressure from
the international community. To this day, not all the items have
been recovered.
The only result of such an act in SG is to open more opportunities
for high-level criminals to stash their fortune to escape the
law.
