Causes
The causes of the New Mexico Penitentiary riot are well documented. Author R. Morris wrote that "the riot was a predictable incident based on an assessment of prison conditions".
Prison overcrowding and inferior prison services, common problems in many correctional facilities, were major causes of the disturbance. On the night of the riot, there were 1,136 inmates in a prison designed for only 900. Prisoners were not adequately separated. Many were housed in communal dormitories that were unsanitary and served poor-quality food.
Another major cause of the riot was the cancellation of educational, recreational and other rehabilitative programs that had run from 1970 to 1975. In that five-year period, the prison had been described as relatively calm. When the educational and recreational programs were stopped in 1975, prisoners had to be locked down for long periods. These conditions created strong feelings of deprivation and discontent in the inmate population that would later lead to violence and disorder.
Inconsistent policies and poor communications meant relations between officers and inmates were always in decline. These patterns have been described as paralleling trends in other U.S. prisons from the 1960s and 1970s, and as a factor that moved inmates away from solidarity in the 1960s to violence and fragmentation in the 1970s.
