Watch Full Movie Online. Preschool to Prison is a compelling examination of how the United States public school system is built and operated like prisons. Zero-tolerance policies are used to justify suspension and arrests that set up a pathway to send children of color and children with special needs from school to prison. Children are being suspended, restrained, dragged, physically manhandled, and subsequently arrested for minor offenses such as throwing candy on a school bus. These personal accounts from people affected by the school-to-prison pipeline give riveting tales about the generational impact on society.
