English: It thus merits further reflection which, at a time in which the ambivalent reports on ECHELON are evoking shades of Big Brother, should probably go into greater detail on the means and methods to be used, on the one hand, to safeguard the rights of the individual, and on the other hand to facilitate an effective but at the same time correct and legitimate suppression of crime.
Spanish:En consecuencia, cuando las contradictorias noticias sobre ECHELON evocan el fantasma del Gran Hermano, merece una ulterior reflexion que probablemente debera ser mas global sobre los medios y los sistemas a traves de los cuales, por un lado, se han de proteger los derechos de las personas y, por otro, se ha de permitir una eficaz y a la vez correcta y legitima represion del crimen.
