We conduct a detailed doctrinal and empirical study of the adverse effects of parole on the constitutional rights of both individual parolees and the communities in which they live. We show that parolees’ Fourth, Fifth and Sixth Amendment rights have been eroded by a multitude of punitive conditions endorsed by the courts. Punitive parole conditions actually increase parolees’ vulnerability to criminal elements, and thus likely worsen recidivism. Simultaneously, the parole system mitigates the rights of non-parolees: family, co-tenants, and communities more broadly. We show that police target parolee-dense neighborhoods for additional Terry stops, even when income, race, population and single-family status are accounted for. Furthermore, police take advantage of the permissive parole search jurisprudence, conducting more searches and arrests of both parolees and their non-parolee neighbors. Combined, this analysis shows that parole institutionalizes individuals and marginalizes communities.
