Interesting cite.  So this is what the USA "Miranda" warning
("You have the right to remain silent.  Whatever you say
may be used against you.") is all about.  The USA Fifth
Amendment protects the right to remain silent on a topic
(here, decryption of something), and also protects the
ideas one might state on a topic if the Government learns 
one's ideas as a result of giving one special protection
for not remaining silent (here, whatever would be found by
decryption if the Government does not independently already
know pretty much what it is).
