The idea of parole and probation was to reduce the number of people in prison, but states are spending millions on incarcerating people for technical violations of their supervision agreements. In Iowa, for example, 40% of the prison population is made up of parole and probation violators. And, 56% of all new prison admissions are for supervision violations -- 22% of them technical violations.
The state of Iowa could reduce its incarcerated population by 5,427 and save $360,400,064 by doing so -- all without a major impact on public safety, according to the ACLU of Iowa. The organization, along with ACLU affiliates nationwide, recently released a blueprint to reduce mass incarceration in the state.
