Wikipedia
Self-incrimination is the act of exposing oneself (generally, by making a statement) "to an accusation or charge of crime; to involve oneself or another [person] in a criminal prosecution or the danger thereof." Self-incrimination can occur either directly or indirectly: directly, by means of interrogation where information of a self-incriminatory nature is disclosed; or indirectly, when information of a self-incriminatory nature is disclosed voluntarily without pressure from another person.
In many legal systems, accused criminals cannot be compelled to incriminate themselves—they may choose to speak to police or other authorities, but they cannot be punished for refusing to do so. The precise details of this right of the accused vary between different countries, and some countries do not recognize such a right at all.

However by 1989, if you signed up for an extracurricular activity in school or applied for a minimum wage job, you could be asked to forego your right to privacy, protection from self-incrimination, Constitutional requirements of reasonable grounds for search and seizure, presumed innocence until found guilty by your peers, and that most fundamental right of all: personal responsibility for your own life and consciousness.
