Should we still be free from self incrimination?:
The difficulty in answering yes and no questions is not so much the specific question and the honest answer, but the implications of that answer.  The only way to respond is to give the correct answer, and then have the defense attorney cross examine for the full explanation.  Do you like chocolate ice cream?  Yes or no.  The asnwer does not imply that you do not like vanilla.  So it is with personal and embarrassing questions too.  It is the implication of the answer that is the problem.
