How did Trina become pregnant, according to the text?

Trina's pregnancy is described as a deeply tragic consequence of her being raped by a correctional officer while in custody. This situation underscores the power dynamics and vulnerabilities that exist within the prison system, where those in authority exploit and abuse individuals who are already marginalized and in a desperate situation. This harrowing event highlights the systemic failures in the justice system, especially regarding the treatment of female inmates, and brings attention to the urgent need for reform to protect vulnerable populations. The narrative around Trina’s experience illustrates the devastating impact of violence within correctional facilities and is emblematic of broader issues that Bryan Stevenson addresses in "Just Mercy."
