Preventive detention is an imprisonment that is putatively justified for non-punitive purposes.
In contrast to this, under preventive detention the government can imprison a person for some time without a criminal charge. It means that if the government feels that a person being at liberty can be a threat to the law and order or the unity and integrity of the nation, it can detain or arrest that person to prevent him from doing this possible harm. Some jurisdictions allow preventive detention only in specific cases, for example only for persons who have already been sentenced for a serious crime (or as part of the sentence for that crime).
A related, but different form of detention is detention of suspects. In contrast to preventive detention, detention of suspects must quickly be followed by a criminal charge (or happen after the charge).
In most jurisdictions, people suffering from serious mental illness may be subject to involuntary commitment under mental health legislation. This is undertaken on health grounds or in order to protect the person or others. It does not strictly speaking constitute a form of preventive detention, because the person is detained for treatment and released once this has proved effective.
Famous quotes containing the words preventive and/or detention:
“Whether in the field of health, education or welfare, I have put my emphasis on preventive rather than curative programs and tried to influence our elaborate, costly and ill- co-ordinated welfare organizations in that direction. Unfortunately the momentum of social work is still directed toward compensating the victims of our society for its injustices rather than eliminating those injustices.”
—Agnes E. Meyer (1887–1970)
“I would like you to understand completely, also emotionally, that I’m a political detainee and will be a political prisoner, that I have nothing now or in the future to be ashamed of in this situation. That, at bottom, I myself have in a certain sense asked for this detention and this sentence, because I’ve always refused to change my opinion, for which I would be willing to give my life and not just remain in prison. That therefore I can only be tranquil and content with myself.”
—Antonio Gramsci (1891–1937)
