Can you explain the concept of preventive detention as mentioned in the text?
Preventive detention, as mentioned in the text, is a legal measure that allows authorities to detain an individual for an extended period of time without necessarily charging them with a crime. This type of detention aims to prevent potential criminal activities or acts of violence by apprehending individuals who may pose a threat to public safety or order. The provisions in this context outline the circumstances under which a person can be detained, the class or cases for which longer detention periods are allowed, and the maximum period of detention in certain situations. Additionally, it specifies that an Advisory Board will oversee these detentions and set procedures for their inquiries.
