Abstract
In this chapter it is analyzed that how issues of internal security and good order in prisons can enter in conflict with the rights of inmates; in many cases these security measures are logical constraints, appropriate and proportional, but in others these should be considered as mere arbitrariness of the Administration without any basis. Particularly, the actuation of the Spanish Ombudsman is studied.
