“All safe deposit boxes in banks or financial institutions have been sealed… and may only be opened in the presence of an agent of the I.R.S.”
– Attributed to President F.D. Roosevelt, 1933 after making it illegal to own gold [There is dispute about this quotation, but the result was the same.]
2010 Update: Great article on President Roosevelt confiscating – a.k.a. taking or stealing – gold from United States citizens and foreigners (through devaluation).
