Another serious consequence of overcrowding is that it makes it impossible to classify inmates by categories, such as, pretrial detainees and convicted persons, which is a breach of Article 5.4 of the American Convention and of the duty of the State to treat pretrial detainees differently, in accordance with the presumption of 386 innocence. Additionally, as has been noted above, saturation of prisons and detention centers can lead to holding people in custody at police stations or other facilities that are not designed, nor are suitably staffed, for housing people for an extended period of time. 290. Moreover, under international human rights law, overcrowding of persons deprived of liberty in itself could constitute a form of cruel, inhuman or degrading treatment, violating the right to personal integrity and other internationally 387 recognized human rights.
