If the police, legal and illegal violence, was systematic and used against enemies and critics of the regimen in extreme cases and situations in which the generals in the power felt themselves threatened particularly, the monitoring on the civil society and the information were constant. The obsession for monitoring as form to prevent the performance ' ' subversiva' ' , over all in what the manuals of the Doctrine of National Security called ' ' propaganda subversiva' ' ' ' war psicolgica' ' against the democratic and Christian institutions: ' ' in a military dictatorship, guided for the Doctrine of National Security, to arise itself in weapons against the regimen it constitutes a crime gravssimo' ' (CHIAVENATO. 1994:118), finishing for generating a logic of the suspicion. I consider that although the dogmatismo, reflecting the marxism and the moral rules of the PC of the B, ' ' The press alternativa' ' , mainly the alternative periodicals politicians, had perceived the perigos presumptions of the increasing Brazilian indebtedness, still in 1973, (the Guerrilla of the Araguaia already was fought), offering a chance so that the aggravation of the social iniquities, that in the region of the Araguaia was so visible and sensible, was divulged. More than two decades of military governments had only accented these trends. In the combat to ' ' subverso' ' on behalf of ' ' security nacional' ' the military regimen curtailed the liberty of speech, kept the press under formal censorship during seven years, 13 pursued and assassinated journalists. The Guerrilla of the Araguaia was marked by the gag of the censorship of the Military dictatorship that feared, in case that it were divulged by the medias, the adhesion to that they opposed in the city that regimen of exception commanded for the military, becoming hegemonic the imposition of ' ' silncio' ' regarding the conflict.
