Alternatives to imprisonment
Academic studies are inconclusive as to whether high imprisonment rates reduce crime rates in comparison to low imprisonment rates. While they at least remove offenders from the community. there is little evidence that prisons can rehabilitate offenders or deter crime. Some inmates are at risk of being drawn further into crime. They may make friends with other criminals, have their medical or mental health needs neglected or endure further abuse from other prisoners and even staff. If they are supporting a family, they will suffer from the parent's absence. Released prisoners commonly have difficulty finding work and earning a legal income. As a result, most countries have high recividism rates. In the United States, 67.8% of released prisoners are rearrested within three years and 76.6% are rearrested within five years.
