Cela repose sur trois principes : un, on informe la victime sur les programmes auxquels le criminel participe, à quelle fréquence; deux, on regarde si, pendant sa période d'incarcération, il a fait preuve d'indiscipline, de discipline, s'il a commis des actes criminels et s'il a été puni; et le troisième élément est ses déplacements d'un pénitencier à un autre ou ses sorties, accompagné ou pas.
It embodies three principles: one, the victim is informed of which programs the criminal is taking part in, and how often; two, it can be seen whether, during his time in prison, he has shown discipline or not, whether he has committed criminal acts and whether he has been punished; and third, it can be seen whether the criminal has moved from one penitentiary to another, or his releases, and whether he was alone or not.
