LA Noire features a system where you interrogate suspects by asking them questions, and then either accepting what they say as truth, doubting them, or accusing them of lieing (which requires proof to back up your accusation).
After each question has been asked, the question is crossed off in your notebook with either a tick (correct) or a cross (incorrect) next to it;
Once you have asked a question, is it possible to re-ask it if you get it wrong? Are your choices in LA Noire final?
