Ethical Dilemma
Situation 1

Your first big case is a multiple murder. As defense attorney for Sy Kopath, you have come to the realization that he really did break into a couple's home and torture and kill them in the course of robbing them of jewelry and other valuables. He has even confessed to you that he did it. However, you are also aware that the police did not read him his Miranda warning and that he was coerced into giving a confession without your presence. What should you do? Would your answer be different if you believed that he was innocent or didn't know for sure either way?
