Final answer:
The sentence that best illustrates why innocent people might be sentenced to prison points to systemic issues, including presumptions of guilt, poverty, and racial bias. These factors, alongside economic interests in the prison-industrial complex, contribute to the over-incarceration of marginalized groups. The dramatic increase in prison populations over four decades highlights these systemic failings.
Step-by-step explanation:
The quotation from the excerpt most helps readers understand why innocent people are given prison sentences is "Presumptions of guilt, poverty, racial bias, and a host of other social, structural, and political dynamics have created a system that is defined by error, a system in which thousands of innocent people now suffer in prison." This sentence points to the multifaceted nature of the criminal justice system's failings, which include a combination of assumed guilt, economic disadvantages, racism, and various systemic issues that collectively contribute to the wrongful conviction of innocent individuals.
Angela Davis, a notable scholar and activist, emphasizes the role of race and poverty in the expansion of the prison population, rejecting the idea that this increase is solely due to better law enforcement. The concept of the prison-industrial complex suggests that financial interests in the incarceration system drive this growth, often at the expense of justice and fairness, especially for marginalized groups.
Federal statistics also show a dramatic rise in prison populations from 200,000 inmates in 1970 to 2.2 million over the next four decades. This increase, coupled with the evident racism and socioeconomic bias, suggests an alignment with Davis's perspective that society too often opts for incarceration as the default response to social problems such as poverty and drug addiction, disregarding more humane and rehabilitative approaches.
