The above diagram from the trial transcript shows that when she was arrested on December 1st, Parks was sitting in the constantly changing middle section, in the first row after the “Whites Only” section. When the bus was full and more white passengers wanted to get on, Blake asked Parks and everyone else in her row to get up so that the white passengers could sit down. The other passengers got up. Rosa Parks did not. Blake called the police who arrested her for disobeying an order from the bus driver.
