Guards and other authorities may use verbal abuse as a means of frightening or demoralizing prisoners to make them more compliant, or simply out of sadism. Enablement of sexual violence Prisoners are sometimes intentionally housed with inmates known to have raped other prisoners, or protection from known rapists may be purposely withheld from the prisoners. These practices create a very high incidence of rape in US prisons, which was the topic of the 2001 report No Escape from Human Rights Watch.
