Shemar is walking home from work when he is stopped by Officer Washington, who matches him to a vague description of a robbery suspect given by a witness. Without informing Shemar of the reason for the stop, the officer begins asking him where he was earlier that evening. When Shemar hesitates to answer, Officer Washington raises his voice and tells him that refusing to cooperate will "only make things worse." Feeling pressured, Shemar confesses to being near the area of the robbery, though he denies any involvement. The officer then arrests him and takes him to the station for further questioning. At the station, Shemar asks to call his attorney, but the officers delay his request for several hours while they continue to interrogate him. Eventually, feeling exhausted and intimidated, Shemar signs a confession, which is later used as the primary evidence against him at trial. Shemar's attorney argues that his due process rights were violated. How did Officer Washington's actions potentially violate Shemar's rights under the Fifth Amendment, particularly regarding self-incrimination and coerced confessions
