Harper Lee uses a variety of different ways to create tension in the trial scene. She starts by making Atticus question Mr Tate Heck several times, even though he is being persistent with the same question. This creates tension as it makes the reader believe that Atticus has found a loop hole in the case, to prove that Tom Robinson is innocent.
Even when the trial is starting, white people still have 'supremacy' over the black people. This is shown when everyone is entering court, as the white people are let into the court room before the black people. This is also shown when Tom Robinson is addressed in court, as he automatically bows his head to the person talking to him. When in court, the black people are sent to sit on the balcony, when the white people sit on the bottom floor. Jem, Dill & Scout sit with the black people on the balcony because they are not supposed to be in court. The children are classed as 'unwanted' so it is ironic that they are placed to sit with the black people, as it shows that they are perceived as unwanted too.
