At the end of her shift, a 19-year-old shoe sales- person was questioned by two store security of- ficers. She was questioned in a small room for three hours. One of the security officers sat be- hind her on the right side where she could not see him (she was blind in the right eye). She was asked to sign a document stating that she was voluntarily waiving her "rights," including the right to remain silent. When she asked for fur- ther explanation of the document before she signed it, she was told that it "doesn't mean anything" unless you've "done something wrong." A security officer threatened to call the police and have her jailed unless she signed a confession. She was told that the interrogation could last all night and that if she signed a con- fession, she could probably keep her job. Under these circumstances, she signed. She was fired two days later. What should the court decide? Why? (Smithson v. Nordstrom, Inc., 664 P.2d 1119 (Ore. App. 1983))
