Abstract
In a world with an overall growth rate becoming more alert, marked not only by advanced and remote communication possibilities but also by a complex and organized crime phenomena, it is essential to define a boundary between the citizen's right "to be left in peace" and the state's right to intervene in the private and family life of its citizens, whenever this is necessary to gather a foundation of evidence for a criminal charge.
Consequently, this paper aims to examine on the one hand, the right to respect for private and family life a state must grant its citizens (for this analysis, the correspondence issue), and on the other hand, in what conditions a state can take actions in order to safeguard its interests and the public security and safety.
